The Blackberry is mainly designed for email. Its main advantage is that emails are pushed to the device so you get them immediately. The Blackberry is not so good as a phone or general mobile computing device as the P900. Also the Blackberries push services are going to be made available on the P900 later this year.
langdona. . .this is incredible news. Do you know whether this will require hardware of software upgrading for the P900. Currently I carry both the P900 and a Blackberry but as you can imagine carrying one would be a good deal easier. Where have you read about this? Thanks
