I'd disagree. The OS's capabilities are actually pretty good imo. I used my wife's HTC Trophy for a few weeks and was a bit bummed to go back to my iPhone. The apps story is night and day though -- there just aren't as many high quality apps and that's where WP7 is hamstrung.

As far as developer experience, I don't do android, but it's so much easier writing and debugging WP7 apps than iOS, from the tools to the simple managed/unmanaged aspects.

That said, Mango isn't going to change things dramatically. It's a good update, but the apps and perception are the problem. Going to be a long haul for WP7, but I hope MSFT sticks to it because it is a good mobile OS.
