Picked up a very cheap, but workable BT adapter (I've got a Lenovo S10 w/o an internal BT module installed...yet). Has a small footprint and comes with BlueSoleil software/drivers. Haven't tested the range, but can sync mail and music from the Fin easily. Transfer rate is somewhat slow (37KB/s), but I'll adjust that later. If you don't have a BT adapter on your lappy or DT, this is a pretty good item at a very resonable price. It's on Amazon here:

I just loaded OS X on the S10 (dual boot with XP) and I've got some tuning to do. I'll also give the lowdown on the Fin syncing with OS X in short time.
Update: No email sync. I guess we'll have to wait for PC Studio. File transfer and push work in Windows. File transfer only under Mac OS X Leopard.
