I bought wp7 for developement (and possibly to replace my aging storm2) and I can say it's not a replacement for a mobile poweruser, definately not a replacement for blackberry. WP7 is very limited in almost everything it does

-everything goes through zune. Wanna develop an app? install zune. wanna copy your movie to your phone? install zune. don't forget to convert your mp4s and wmvs to zune format first tho! or it won't play.
-won't synch email when it's idle
-most of the apps created are silverlight applications. very limited in functionality, they mostly "list" things and generally textbased with pictures thrown in. Good luck finding a super app
-no instant message app. get this phone say bye bye to yahoo, aim etc.
-no multitasking (explains lack of IM apps)
-and a whole bunch of other annoyances
On the other hand it does a few things quite well. I like the facebook app, it's the best i've seen on any phone, games are excellent as well. Its a great phone if you want a phone with facebook and gaming but for productivity look elsewhere. This is not it.
