Well, I've gone and done it. I got an HD7 for free from Wirefly. I should get it on Thursday. I'll post my first impressions after the weekend. If there's enough to be said, maybe I'll do an article on my experience switching from Android to Windows Phone 7.
I wonder, how many people have adopted WP7 since it was launched? Actually, I don't know anyone who would switch to it. But I tried it once and I think this platform is not worse than others. For me it's just a matter of a habit -- I've already got used to Android)
