I tried upgrading to Gutsy on my old Dell D800 today, it took about 7 hours to download the packages and then the upgrade failed. It couldn't get the screen resolution right and didn't detect my graphics hardware. The CD does it just fine. So I wiped the root partition and did a clean install. That seems to work fine. The wireless configuration was effortless. Now to figure out all the packages I need. I should keep some notes on the changes I make too.
