> WP7 has the best development story. Android is really the odd man out, with nothing going for it in this race, other than its current momentum.

A rooted Android device has more going for it than either of the other two, as far as I can tell. The problem is that a non-jailbroken Android device is kind of gimpy -- and I don't currently have so much need of desktop power in my pocket that I'm willing to void my warranties.

I suspect that, in the long run, the real value of Android will be that it spurs further interest in open source OS development and commercial use of such software on mobile platforms. We just need the hype around the Android platform itself to give way to such development; at that point, we'll get more power and flexibility than all four of the current primary mobile software platforms combined (Apple iOS, Google Android, Microsoft WP7, and RIM Blackberry). At least, I hope so. If that doesn't happen that way, I guess we'll just have to wait a decade for such an endeavor to bear fruit under some other circumstances, and in the meantime we can all be pathetic with our gimpy pocket OSes.
