I have had lots of Windows Mobile phones in the past I switched from a Touch Pro to this BB Curve. So far I am liking it. I really like the size and feel. I had a couple of treos so I am used to the forum factor so that wasn't an issue. To answer the OP's question if I don't like the Curve I will eventually be switching back to a Touch Pro.
