And this is exactly why MS will eat blackberrys lunch. Just wait until enterprise clients can order the Dell optiplex win phone 7 that acts just like a desktop as far as the IT staff is concerned. The first VS dev that shows a dashboard app that displays KPIs from the CRM to an executive will seal the fate of blackberry in that company. The only really powerful lockin that BB has is Pin to pin or BBM as I think they call it now. Phones arent yet powerful enough that a phone from 3 years ago still performs adequately, there are probably 3 or 4 cycles left to really change hardware/OS market share.
