IF and its big IF, they can get a real word processor, spreadsheet and PDF handler into their OS, and more fully enable bluetooth and the USB port, they may have a shot with the companies already using BB phones. If not, those companies will likely migrate away from the PB AND also from BB phones as they swap those out over time.... It may be a win/win or lose/lose situation for RIM.
DTG is decent for anyone that needs to read or do quick edits. ANYTHING past that, and I mean anything, the application. The sad part is, it only needs to be slightly improved to match the Android/iOS versions. BT and USB Host mode will be enabled, HOPEFULLY in the next official release. That along with BB Fusion which allows anyone with a BES (5.0.3) to activate a Playbook on the BES will go a long way. They also need to make sure they give free upgrades to 5.0.3, and if possible BB Fusion away for free to existing BB customers. Keep em happy.
