Windows Phone 7 in-depth preview (by Engadget)

Overall look and feel
As before the "Metro" UI is in full effect here, meaning lots of very 2D, stark blocks of color and text. Actually, 2D isn't quite right -- the interface utilizes a lot of layers within a single page, so when you're swiping through menus you get a kind of parallax scrolling effect reminiscent of 16 bit side-scrollers (think Castlevania for the SNES). It actually works really well here, giving a sense of depth and detail but not detracting from the content Microsoft is putting up front.

This is probably the most accurate and nuanced touch response this side of iOS4. It's kind of stunning how much work Microsoft has done on the user experience since we first saw this interface -- everything now comes off as a tight, cohesive whole. It really put one of our major fears about Windows Phone 7 to rest.

The overall navigation of the UI to be really quite intuitive, despite the fact that a good number of options and in-app menus are accessible only through a long press... something you're not really made aware of in most cases. The long press becomes a bit like the skeleton key of the OS -- you just have to try it and see what kind of functionality it unlocks. Once you get into the habit of holding down on items instead of wildly searching for the next screen or tile, it makes a lot of sense, but it does take some getting used to.

Windows Phone 7 relies on a drop down, Android-like window shade to show when you've got a new SMS message, so Microsoft is already besting Apple there, and if you're playing music in the background, you're able to bring up your controls by tapping one of the volume buttons. Weirdly, that same area up top is used to show your signal, battery, and WiFi status, but it only drops down if you touch or swipe the upper part of the screen.

Keyboard
Let's just put this up front: the keyboard in Windows Phone 7 is really, really good. We're talking nearly as good as the iPhone keyboard, and definitely better than the stock Android option. It's one of the best and most accurate virtual keyboards we've used on any platform -- and that's saying a lot.

The WP7 keyboard is as simple and clean as the rest of the OS, showcasing little more than rows of monochromatic keys (white on black or black on white depending on your app), which pop-up a letter above them when depressed. Hold on a key and you get additional options for accents, just as you'd expect. The general layout offers a familiar placement of the shift, return, and number / punctuation keys, but adds an emoticon button as well.

Contact management and social networking
Windows Phone 7 doesn't have "contacts," per se -- it has a People app, and there's quite a difference. This is a thoroughly social platform, and it doesn't really seek to make any sort of differentiation between people you talk to / text / email, those you just casually observe, and those with whom you're "friends" in name only. If that kind of philosophy reeks of Motorola Blur or Palm Synergy, you're on the right track; as soon as you add a Windows Live, Exchange, or Facebook account, it pulls in every contact associated with that account and disperses associated content throughout your entire phone.

If you've got a lot of Facebook friends, this renders your People app all but useless as a traditional phone contact list. So, say you're looking for someone's phone number: if you're a normal human being with maybe a couple hundred or fewer actual contacts, you're used to just flicking through your contact list to get to whomever you need. With Windows Phone 7, though, Facebook has puked all over that list, so Microsoft instead recommends you search for what you're looking for (matching names filter as you type), pin extremely frequent contacts as tiles on your home screen, or make use of People's Recent list, which auto-populates with contacts that you've recently used.

Email and messaging
As with most smartphones these days, email setup in Windows Phone 7 is relatively automated and painless, and there are plenty of options to go with most people's leanings. When you initially boot the phone, you're asked to provide a Windows Live ID, though it's not necessary to use one. On the email setup screen, you're provided with self-configuring options for the aforementioned Live, Outlook, Yahoo! Mail, and Gmail. You also get options for manual setup of POP or IMAP accounts. As heavy Gmail users, the option was obvious for us, and you'll be happy to know that Microsoft provides full (well, almost full) EAS support for Google accounts.

The email app on the phone is pretty terrific on the whole, providing a clean, clear layout and upfront options for your most-used functions. In the standard inbox view you get your emails with one line of a message preview, and you can swipe right or left for sorting options by unread, flagged, or urgent (on top of the standard folder view). We found the inclusion of the unread view especially helpful when triaging our inbox. Multiple message management is executed here better than most mobile email apps we've used, requiring only that you tap to the far left of a message to engage your checkboxes. It definitely sped up the process of killing or moving mail. Also nice was the fact that in a standard message view, when you delete an email you're kicked back to your inbox -- not to the next message.

Tapping the search button while in mail gets you to a pretty powerful search which parses subjects, message content, senders, and receivers all at once. It made it astoundingly easy to find what we were looking for with almost no hesitation.

Browser
For as much crap as Internet Explorer gets (less, admittedly, now that the debacle of IE6 is finally starting to fade), we've got to say that web browsing on Windows Phone 7 is actually a really pleasant experience.

There isn't a lot of bonus functionality, but we appreciated the "pin to start" option that lets you turn a page into a home screen tile, complete with a miniaturized view of the site (of course, there are standard bookmarks available as well). Tabs are also supported; on our test device, they were limited to a maximum of six, which we would assume will be true of all Windows Phone 7 devices -- but let's be honest, you probably don't need more than six open tabs at a time on your phone, and if you do, you should be in front of a laptop anyway. The tabs all continue to load independently regardless of whether they're active or not, which is nice, and doesn't seem to have much of a negative impact on overall browser performance.

Zune
The Zune integration is rather seamless on Windows Phone 7, allowing you to browse and play what you have in your library, sync music and video back and forth to your PC, and if you have a Zune Pass subscription, you can grab whatever you like (well, almost) right on the phone without hesitation. We love having almost limitless access to new music on a phone, and the Zune Pass subscription certainly adds that capability, though you're adding another $14.95 on top of your existing phone bill if you decide to go that route. Ultimately it's a question of how voracious of a music buyer you are -- but something tells us we're going to see a marked increase in Pass users when these phones hit the market.

One other important aspect to note about Zune and Windows Phone 7 is that the desktop software and these devices are now extremely interconnected. Not only do you use the Zune software to sync your music and videos, but you'll be able to buy apps from the marketplace on your computer, you can sync photos in the Zune application, and your general account and device management is handled through the app now. Microsoft has always been good about syncing, but this makes the process slightly less obtuse than its ActiveSync options from the Windows Mobile heyday.

Camera and photo management
We'd heard before that one of Microsoft's big goals for Windows Phone 7 devices was stellar camera performance -- not just in terms of picture size and quality, but speed, too. It seems like they're making good on the promise so far -- on the Taylor, we were regularly clocking about four seconds from camera button press to the first shot, and around two seconds between shots. We didn't evaluate the pictures or video for quality since we're dealing with hardware that'll never be released, but needless to say, Windows Phone 7's minimum specs should ensure that you're getting at least moderately decent shots no matter what device you choose.

Once you take a shot, something pretty cool happens: it advances to the left, almost as though you're looking at an actual roll of film, and you can see a dimmed sliver of the shot you just took on the left side of your viewfinder. You can then swipe to the right to see shots you've taken in the past, starting with the most recent, and returning to viewfinder (camera mode, as it were) is as simple as swiping all the way to the left again. It's a neat user experience that we suspect novice users will pick up on very quickly. The available camera options and modes can be extended by phone manufacturers, but the default list is pretty impressive and includes configurable white balance, image effects (grayscale, sepia, and the like), saturation, ISO, exposure, and even metering mode -- and most of these options are still available even when capturing video. Naturally, you can also set the flash to fire automatically, always, or never.

Once you've taken your shots, the phone can be configured to automatically upload them to your Windows Live SkyDrive account in the background with your choice of privacy level (private, friends only, or public). You can also zip pictures over to your Facebook account using a menu item in the Pictures app, but interestingly, you have to choose between "upload to SkyDrive" and "upload to Facebook" menu items in the app's settings.

Speaking of the Pictures app, this is your one-stop shop for imagery on the phone -- both your shots (locally and from supported online services) and those of your friends show up here. You'll come here to view and send pictures, change your lock screen wallpaper, and -- because this hub is extensible -- use any third-party services that developers have plugged into it. In a way, it's kind of the prototypical Windows Phone 7 app "hub" in that it cycles through your own pictures for its background and has some cool time-dependent features; for instance, it adds a "moments" page that summarizes pictures on the phone that were taken in the current month.

Marketplace
Microsoft has already started handing out prototype Windows Phone 7 devices (the same ones we're reviewing here, actually) to developers, and it's going to continue to do so in liberal quantities as it gets closer to launch -- oh, and the side of the box says "developers. Developers! DEVELOPERS!!" on it. So yeah, you might say that Redmond understands full well how important third-party apps are going to be to the success (or failure) of this platform. Those will end up being exposed through the Marketplace hub, which as you might expect, is a thoroughly different experience than the one you might be used to on Windows Mobile 6.5. Instead, you get something more akin to what Apple and Google are offering -- with a few twists.

The first thing you notice when you open the Marketplace is that you've got music as an available category, whereas iOS breaks it out into a separate iTunes app and Android leaves that to third-party providers like Amazon. It's not quite as integrated as you think, though -- tapping on music just bounces you out to the Zune Marketplace, which is fine since you wouldn't want two disjoint places to purchase tracks anyway. Likewise, hitting the games category sends you over to the Xbox Marketplace, which sadly isn't live yet and wasn't available to test.

That leaves us to the final category: apps. Though there's just a light smattering of Microsoft-built demo apps available in the Marketplace at this point, it was enough for us to get an idea of the purchase process. Tapping on it takes you into a separate marketplace hub that, by swiping around, gives you the typical views you'd expect: newest, most popular, and featured. You can also search by pressing the phone's hardware search button; on the plus side, it searches across all of Microsoft's marketplaces so you get apps, games, and music in your results, and that's kind of cool.

Office
Tight Office integration, complete with an awesome on-phone document and viewing experience, stands to be one of the biggest differentiators for Windows Phone 7 -- a feature that could almost singlehandedly make these devices impossible to ignore for serious business users regardless of their seemingly consumer-centric slant.

Though Word seems to do a decent job rendering pages onto the small display, the editing capabilities are weak at best -- you can't change fonts, for example, and you can only choose from four font colors: orange, green, red, and black. Though there's a spell-checker (you'll recognize the familiar red squiggly lines), there's no copy / paste capability -- and in an app like this, it's hard to imagine being too productive without any sort of clipboard whatsoever. Excel seems similarly gimped, though it's got a pretty solid set of built-in functions; we don't know what percentage of the full app's functions are supported, but it's a long list.

PowerPoint documents, meanwhile, can't be created on the phone at all. And really, that's totally fine -- if you're creating your presentation that you have to give in half an hour on your phone during your train ride into the city, you've probably already blown it. The important thing with PowerPoint is probably the slide show capability -- especially for retail devices that have TV-out -- and in that regard, it seems to do just fine (cheesy transitions and all).

Xbox Live

As we stated above, there really isn't much in the way of Xbox integration on the device right now. You can add your Live account and you get your avatar into the phone... and that's about the extent of it. We're hoping that before long Microsoft shows off just what these devices will be capable of. We were told by Joe Belfiore during a meeting that there would be two kinds of games on Windows Phone 7 devices -- turn based, "app" games, and Xbox Live content which would be full-on arcade experiences.

Maps
Microsoft's Bing Maps implementation on Windows Phone 7 is pretty great -- they've done a fantastic job of blending the experience of using a mapping app into their so-called Metro design language. You've got access to satellite imagery and real-time traffic information; location fixes happen quickly, though we found that they tended to be a little less accurate than Google's when indoors and out of GPS reception. Pinch-to-zoom is smooth and fast, and we liked the almost ethereal appearance of the map tiles as they loaded after panning or zooming in -- it's hard to describe, but it's a pretty neat (though admittedly unnecessary) effect. Likewise, we liked the zoom-out, zoom-back-in effect when locating your position on the map while a different area is being displayed, which gives you a better idea of your relative position than the iPhone's rapid scroll.

Since this is straight-up Bing Maps on the back end, you can expect the same database of locations here that you get when you search for stuff from your computer. On the phone, you can search either by text or voice (more on this later), which will call up pushpins for matches near your map view. As you'd expect, tapping a pin brings up the name of the result; a second tap calls up a page of information where you can find a phone number, URL, average rating, and even hours if they're available -- this is extremely handy for restaurants since it can save you an awkward trip to the business' inevitably non-mobile-friendly website. Swiping around calls up a screen with nearby points of interest, and another screen with individual reviews; Microsoft is aggregating several sites for these, and we regularly found entries from both Citysearch and JudysBook.

Our favorite part of Maps, though, has to be the directions list when navigating to a destination. It's no voice-guided turn-by-turn navigation, of course, but the app has a cool split-screen mode that shows the list at the bottom and the map corresponding to the currently-selected list item at the top. As you swipe through the list and highlight different items, the map moves around -- in other words, you can quickly see where (and how) you need to turn. Both pedestrian and car modes are available.

Search
Like Maps, Windows Phone 7's search capabilities are naturally powered by Bing. Microsoft has done a neat job translating Bing's well-known home page layout to the small screen, complete with gorgeous rotating imagery and hotspots that reveal factoids when you tap them. There's a mic to the right side of the text box that lets you conduct a voice search, and while we wouldn't bother trying to find anything with an odd name this way, common mobile searches (think "burritos") worked really well. Once you run your search, you get not just web hits, but also news (burritos come up in the news more often than you may think) and local results -- basically a tie-in to Bing Maps that uses your location to find stuff nearby.
