Ubuntu 6.10 is garbage, any RH based linux is also garbage.I am still using ubunti 6.04 (the stable version) and it works fine though.
As far as windows vista goes, any x.0 software will be buggy. Always wait for x.1+. This goes for windows as well.
I wanted to install 6.04 but it wouldn't install on my hardware. It was not compatible with my chipset.
