Great phone generally... i have had this since November 07 and used to have the MDA Vario2 prior to that. Purely for business use

PRO- Easily replaces my laptop in terms of mobility
- The telephone sound is much better than the MDA V 2
- Faster internet access
- Great GPS
- Faster processor
- The keyboard is awesome!!! slide and tilt
- Anti-Virus comes standard as general package with T-mobile


CONS
- Heavier than the old mda v2
- Phone switches off whilst using it -although easily remedied by just using press the scroll button again or even the power button
- The battery life is poor compared to its predecessors

Still feels flimsy and i wouldn't drop this on the floor with the kind of cash paid for it. This phone generally is A GOOD all rounder waaay better than IPHONE!
