I'm very happy with my latest Ubuntu install on the newer Toshiba laptop. Looks like I'm not alone with the thumbs up effect. Only major problem I've had with it so far is that it's not communicating well with my microphone port so I can't use it for Skype or Audacity recordings.

"Every so often I take a stab at Linux, to see exactly what I like and do not like about the OS. Many of its problems, for me, stem from its inability to run on my overloaded hardware, or the occasional driver that makes the OS impossible to use without hand-tweaking something or other. That said, I seriously like the Ubuntu 8.10 implementation and will now install it permanently on my latest machines. It's a winner."
