I only use BT for hands-free connection in the car. Painless, works just fine. I used to also use a pair of Bluetooth-to-serial adapters for programming my empegs -- those also worked very well, over 10 years ago.

The nifty little USB/bluetooth headset I picked up last year (from another thread on this BBS) also "just works" without fuss.

So it's not all bad, just some more demanding uses, and/or with Apple products.
