Isn't Blackberry Unite supposed to turn your desktop into a server that can host files, and images and more importantly full Otlook Sync over the air? That would probably be the answer to Apple's mobile me. If the new touch BB is even half cool, they could put a dent into Apple's strangle on the market.
Overall its widely agreed that there should be some sort of full OTA sync program for the non-corporate user. It can't be that hard to develop.
