Motorola i930 / i920

Anyone had a chance to really use the i930 as a down and dirty PDA? I currently use an HP IPAQ 2215 that I really love, and it syncs great with MS Outlook. But am troubled by all the work of coordinating my IPAQ and Motorola cell phone. Bluetooth data transfer helps, but it's still a pain. The i930 seems like a good idea, but it doesn't have bluetooth for my headset, a feature I really like. Someone said you can get a bluetooth SD card, but I already have a .5 GB SD for data storage and data transfer. Do bluetooth SD cards allow data storage, too? Also, I use a number of 3rd party applications so I don't know how they will work on the i930.
