I have spent almost a week with the HTC HD7 from T-Mobile USA, the first device for the Magenta network to run Microsoft's new and "improved" Windows Phone 7 mobile Operating System. So far, we've taken a look at the hardware, which I was pretty impressed with, even if I had seen other devices much like it already. And then, we took a personal look at the software, and I came out pretty confident in the system, even if there were a few things in there that threw me for a loop. Tonight, we take a look at the apps. As of the time of this writing, Microsoft says they've got just over 2,000 applications available in the Windows Marketplace. I picked out my favorites, and I'm also going to talk about the native ones, too. So let's get into it.
