Just over a week ago I upgraded my laptop (a Fujitsu Amilo Li1718) to Ubuntu 9.04, using the release candidate. I found it to be very impressive. Previously I had had to jump through various hoops to get everything working. Now (hopefully) those days are gone.
A peculiarity of this machine is that for the WiFi to work, the hot keys (well, the wireless hotkey) have to work. The machine also has an ATI Radeon Express 200M video chipset.
