There is a nice review of the Bold over on:

I confused the Bold with the Blackberry's forthcoming touchscreen unit in my prior posts and some of what I wrote doesn't apply (some does).
With respect to Bluetooth, there is a program for Windows Mobile call Blue Music which allows other applications to use your Bluetooth stack and communicate through your bluetooth hand's free. I imagine something like this could be written for the Blackberry.
The problem right now is that Apple has a huge competitive advantage with their dock. Blackberry, Nokia, Microsoft, and Sony should come together on a competing standard preferably something just beyond the boundaries of Apple's patents. This would create a powerful incentive for carmakers and airlines to support this alternative standard.
