If you are running Windows then I am sure this is a great product. BT claims "PC" compatibility and this is re-enforced by Belkin's website and the packaging, which has "multi-platform and Linux compatible" specifically stated.
I have one Windows XP laptop and one Ubuntu Linux PC. You can switch from the laptop to the PC, but the keyboard combination (the only way to switch) then refuses to switch back. After trawling the web in a desperate attempt to get this working I finally gave up after all the sites said "give up, it doesn't work, even though they say it does". So I am currently stuck with a useless KVM.
Beware, the packaging is heat sealed plastic, so, even though it says it is compatible, the only way to find out it does not work is to cut the packaging open!
Belkin's website now offers the Switch2 instead (not offered on BT) which has an independent switch/remote. I suspect this is because of the aforementioned problems and would, I expect, work.
