@Channan: Great points! I would argue though that its not just the amount of apps you have stored on your phone, but the way your apps are integrated with the core infrastructure of the phone thats makes it compelling. If you took all the apps you use and put them on a phone that did more with/made those apps more…

How will Microsoft catch up? I think its a valid concern and something that should be asked. However, its a challenge I don't see MS having much trouble to meet.
