blackberry VS winmobile

the two biggest players in the biz phone market are RIM and MS,
now that both of them offer what seems to be the ultimate biz app (push mail) a lot of company choose one of these two solutions for there out of the office user.
As of today RIM is a winner is the clear winner i think that they are going to keep wining until MS will understand the following:

1. mobile is not desktop- there is no use to give the all windows experience into a small device (and no one need it)
2. single hand operation- phones are made to be used in one hand... when you are using stylus you lose a lot of users.
3. battery consumption- winmobile phones last for 20 hours in the good case most of them ran out of battery after 10.
4. UX- winmobile is much more slower then blackberry and much more complex.

until MS will sit back on the design table and design a phone and not a mini pc. they will allways stay second rate to RIM.
