Perhaps I’m a bit late in posting this, but version 6.10 of Ubuntu was released this week. I highly recommend you give it a go..there’s no need to install anything, you can boot the whole OS from the CD (and then choose to install if you like it). I’m using the live CD now to write this, neat huh?
Even if you can’t be bothered with that, I recommend you find out what all the fuss is about anyway:
Ubuntu is really starting to impress me quite a lot. This latest version comes with almost out of the box support for all those fancy 3d effects you may have seen on Youtube.
