I have an NC110 w/ 12.04. Unity was a show stopper so I reverted it back
to XFCE. The performance is much better. I haven't seen any performance
issues so far, but I do know there was a huge bug with the backlight
controls and some of the other Fn keys. It required a BIOS upgrade to
fix them.

That may have been resolved in 12.04 w/o the BIOS upgrade, but I had
hell with them in 11.10. Drop FreeDOS onto a USB with the BIOS .exe
file, then boot from USB, change to drive C: at the dos prompt and call
the .exe.

You'll need mains power and balls of steel - the NC110 gives off a lot
of system beeps as it upgrades.
