I was getting sick of all the wires on my desk, and I needed a new keyboard anyway,
so I bought a logitech bluetooth key and mouse (mx 5000). It's supposed to work just fine.
The keyboard comes with a bluetooth dongle, but it's rather silly not to use the bluetooth build in my laptop, so i never tried the dongle.
I was running linux-image-2.6.26-1-amd64 on my laptop and it had serieus issues with bluetooth. It was very hard to get the device to pair, it imvolved alot of manual probing/forcing.
This morning I upgraded kernel to 126.96.36.199 from kernel.org and it all started working flawlessly...
P.S.: might be fun to see if I can find a way to have it's LCD display work in Linux ;-)
