Just checked out the video on the Windows 7 site, and I am not impressed. I mean, it looked good, but just don't care for the overall layout. My view may be a little tarnished in that I have never liked Microsoft programs (aside from Office) very much compared to 3rd-party equivalents. I've never found them to be very intuitive and for the most part lack features I was always able to find in almost any 3rd party program. My experience with the PocketPC which had Windows Mobile was a joke, and though Windows Phone 7 is entirely different, I think it will be more of the *same*.
That said, Android is still in its infancy, but it is so customizable and there are enough resources out there in spite of Android's infancy either through rooting and the use of custom roms, or through the 2.1 update and the Android Market that most wants and needs can be met. Sure, I'm jealous of the Netflix streaming app, but as Android continues to grow, it will get its share of enviable apps as well. Besides, as soon as 2.1 hits with Flash 10, the Netflix app won't be necessary... we can just go to Netflix.com and stream whatever we want. So, I'm sticking with my Droid.
