I've been using Ubuntu 8.10 for a while now and it works very nicely indeed
I haven't installed any nvidia drivers because I'm afraid to mess things up and it works fine anyway.
this is a multi-boot system and has really extended to useability and life of my 2002 Dell laptop.
I love how I can plug in my friend's new digital camera and it is immediately seen. no fuss, no muss. Same with BlackBerry phones.
I wish the video editing was more mature, but that will come in time. I love linux.
