I am currently running Ubuntu 10.04 Lucid and am having fantastic results with it.
I recently purchase an IOGear Bluetooth USB Micro Adapter GBU421WM. I plugged it in went to PREFERENCES -> BLUETOOTH and set it up so I could send pics from my phone to my computer.
That was all I did and it works great.
I don't get to help much on here but if I run into something that I can add, I'm doing it.
Thank you Ubuntu for a fantastic OS: 10.04 Lucid.
