|Joshua Topolsky has an in-depth article on Windows Phone 7 over at engadget.|
From the article…
We were extremely surprised and impressed by the software's touch responsiveness and speed. In fact, 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. We haven't seen any substantial lag while using the device, and the short transitions between applications or pages are well suited to the overall experience….
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 phone we had to test with is actually rather narrow despite its screen size (3.7-inches) and resolution (the Windows Phone 7 standard 480 x 800). So while typing was sometimes a little cramped horizontally, it was never a chore.
