Ubuntu, is now up to 12.04 LTS (Long Term Support), at the time of writing, this adds the new Unity interface and quite a few tweeks to the OS.

If anyone here needs a hand to install your own Ubuntu scheme on their computer, by all means post here, Linux is as stable as, in the 18 years I've been using Linux, I've never had a single crash or error message, open source is the way to go, because you have a ton of other people around the world updating the code.
Once these updates come to a head, they are released, they take half as long as any M$ update and they give you a stepped progress using a text based up-dater, while the new files install so you can see what is going on.
