Review: HTC HD7
Social Networking
The HTC HD7 integrates tightly with Facebook, but the experience feels incomplete. The phone automatically synchronizes your Facebook contacts with your address book. There's no way to keep the two separate, and the phone does not support groups for contacts, which is especially odd because even the cheapest feature phones let you group your contacts.
Though the phone doesn't come preloaded with official Twitter and Facebook apps, these apps are available free from the Windows Phone 7 Marketplace. They look very good, in keeping with the rest of the WP7 design. The HD7 has a problem with scrolling, though, and this was most apparent in the social networking apps. When I tried to flick quickly through my Twitter feed, or through all of my friends' updates in Facebook, the list would jump around wildly and occasionally take me back to my original point. Slow scrolling worked fine, but who wants to scroll slowly through a hundred Twitter posts?
Productivity
While I had problems with the Office suite when I tested the Samsung Focus, the HTC HD7 had no such issues. All of my test documents for Word, PowerPoint and Excel came through just fine, and the phone had no trouble opening any of them. Editing PowerPoint slides requires the newest version of Office, which I don't have, but the slides looked great on the HD7's screen, accurate and clear. It was also easy to browse through multiple pages in my Excel spreadsheet and flip through sections of my PowerPoint deck.
Word is the odd man out. My Word document came through fine, and I was able to edit and add text. But the mobile version of Word does not stick to perfect formatting, so your document will be scaled to fit the phone's small screen. If layout is important to you and you want to see how a document will look when printed, Word in WP7 won't help you. But everything else worked fine, including tables and lists.
