Anyone here using a smartphone running Windows Phone 7.5 Mango? Just got an HTC Trophy, and I have to say, Windows Phone is the best-kept secret in smartphones and a very, very good alternative to Apple's iOS and Google's Android. Wrote this lengthy review for a tech forum I'm part of, and I thought I'd repost it here for anyone interested. EDIT: it won't let me just post a url to YouTube and keep it as a url instead of an embedded video. Sorry for the big video boxes breaking the flow. THE GOOD HTC hardware is solid construction and quality materials, though the styling is somewhat drab and anonymous compared to more stylish designs from Apple, Nokia, and Motorola. Windows Phone’s tile-based interface is easy-to-use, self-explanatory, refined, stable, and attractive. For those not familiar, here's a quick overview of what the tiles and some of the native apps look like in action ([ame="http://www.youtube.com/watch?v=L2m3wFWeTIU"]Windows Phone 7 - Intro - YouTube[/ame]). The integrated address book pulls all information from your Facebook, Google, and Verizon address books and puts them all in one place, so I can pull up “Joe Sixpack” and have options to call him, write on his facebook wall, email him, look up his employer (if it’s on a facebook profile), etc. The Mail app works well with Gmail, and has an attractive and easy-to-use interface, though as one nitpick, I can’t figure out how to modify the default (small) font size. I like to email my mother with large text in the email, and can't do that as far as I can tell. It offers native support for Microsoft Office documents—I can open, edit, or even create Word and Excel documents. It's no substitute for a laptop, but it works well in a pinch. It has support for Zune subscription (a fantastic subscription-based music service, better than Pandora or Spotify in my opinion). Zune allows you to download entire albums for free, and not just ten-year-old junk that you don't want. But it can only stay only your Windows computer and Windows phone, and you need to keep your Zune subscription ($10/month or $100/year) active to play it, unless you purchase the DRM-free version (comparably priced to downloads from iTunes and Amazon). A four-minute intro to the phone’s Zune app is here: ([ame="http://www.youtube.com/watch?v=lQaTsj6cZlE"]Zune Integration on Windows Phone 7 - YouTube[/ame]). There's a vast selection of smartphone games on Microsoft’s Xbox Live, some of them very high quality. One great example is “Rise of Glory,” a remarkably-detailed WWI flight sim where you control your plane by banking and yawing the phone ([ame="http://www.youtube.com/watch?v=VziuBsEAx0c"]Xbox LIVE Games on Windows Phone: Rise of Glory - YouTube[/ame]). I love it. No substitute for the surprisingly-similarly-named PC flight sim "Rise of Flight" by 777 Games, but it's a fun distraction when you're sitting on a porcelain throne. The camera is respectable quality and uploading to Facebook or copying to my computer are both easy to do. It's not amazing quality, but it's respectable quality and easy to use. THE BAD As noted above, the solidly-built hardware is lacking any sort of style or flair or luxury. The processor isn’t the fastest. This isn't a big deal for how I use it, but still worth mentioning. Games take a while to load. While the screen is sharp and vibrant when you look at it perfectly perpendicularly, it has narrow viewing angles, so the colors wash out quickly if you look at it from an angle. Viewing angles are far inferior to my Kindle Fire. The Zune PC software, which you use to manage the device and update its firmware (like you use iTunes to manage an iPhone) is Windows-only, whereas iTunes is available for both Windows and OSX. In other words, if you buy a Windows phone, you’d better have a Windows computer as well. My 2011 Civic Si thinks it’s an “unsupported device” and won’t play music off it like it’ll play music off the iPod. (Windows Phone 7 was released after my generation Civic Si was first released in 2006...maybe that's the problem?). While the selection of Microsoft apps (both Microsoft Office productivity apps and Xbox gaming apps) is good, the selection of third-party apps is not nearly as good as Apple’s iOS or Android. CONCLUSION The hardware is perfectly respectable but lacks any sort of flair. It's like driving a new Ford Taurus. Well-made and understated, but don't count on it to draw longing glances from anyone. The screen viewing angles are the biggest issue. Windows Phone 7 is a fantastic smartphone OS. Right now it’s really only held back, ironically, by the fact that it’s not already popular. Since not many people are going out saying “I want a Windows smartphone,” phone manufacturers aren’t building many phones for Windows 7, so there’s not much high-end hardware running it. And there’s not a lot of third-party app developers making WP7 app development a priority. But if Windows Phone is able to develop that critical mass of users to start attracting more hardware options and more apps, it could snowball and become huge, because the operating system itself is great. Even my tech-illiterate wife quickly understood how to use it, the Microsoft Office support is great for business users, and the Facebook and XBox Live integration are great for casual users. Am I glad I got it? You bet. It offered a level of refinement that I haven't experienced in Android phones, and the UI design, Zune integration, MS Office integration, and XBox integration were all advantages over the iPhone, at least for me.
