I've been playing with a Dell Insperon Mini 9 for a while. Dell has released an ISO image for the Ubuntu installation on the Mini 9. So far it has been a painful download, and I still have 2 hours to go. Apparently this is a re-install image so it will wipe the hard drive, so I will have to put some thought into how best to create an image of the current Windows XP installation. Right now I'm thinking of shrinking the partition, then using a live CD to copy the image to some place safe.
I'll have to see, download first.
