Whilst at TechEd I got to play with a Motorola Q - all I can say is Wow!
For those Blackberry users obsessed with their side wheel - you are in for a treat!
The device is very slim and the use of the jog wheel makes single handed operation a reality!
It's a real shame it's CDMA and not GSM as we can't get it in Europe :(
One of my colleagues who has the Q also posted this really interesting article on how to use it as a powerpoint clicker :)
