Asus expect 5 million of these units to ship this year, so it is not good that
1. Wifi still doesn't work by default - requires a patched madwifi driver.
2. Tapping the touchpad doesn't work!!
The first problem is known from F8 and the fix is well known, the second problem is infuriating - it is extremely annoying to have to constantly use the left-click button on a touchpad, especially on the (tiny) asus eee pc.
On top of that, while we have the great livecd to usb conversion scripts, the livecd doesn't contain any compiler tools, so you can't easily compile a wifi driver (The ethernet connection doesn't work either EDIT actually it does, just needed manual configuration for me since I'm not using dhcp)
Other than that, F9 looks quite nice and performs similarly to F8.
