Take if from someone who knows (I have had the T-Mobile MDA, the T-Mobile SDA, the T-Mobile Dash, the HP6313, and the HP6515). If you truly love your Blackberry, everything else (no matter how much "eye candy" it has) will never make you happy. I spent a lot of money trying difffernt devices, and ended up back with a Blackberry. I'm going to upgrade soon, but it will be another blackberry.
