unity (or perhaps all of ubuntu 11) was essentially unworkable for me. i don't know maybe it was the bluetooth mouse, but nothing else has had a problem with it. i never quite got around to getting zenwalk or arch up and running so i was using windows or mac laptops for a good six months, until i discovered bodhi linux, which has been excellent. and i rely on ubuntu discs for doing grub repair/reinstalls but that seems to have become unreliable after ubuntu 9 and broken completely in 11. it couldn't even install and run ubuntu on one dell (though windows still booted right). bodhi linux has worked flawlessly (almost, sometimes applications crash, but they crash clean and in predictable situations, like everytime logging out of gmail for midori). zenwalk works well and its grub installer detects the more popular linux types, and has better wireless in my experience than others bar ubuntu, only difficulty is the lack of (?) a system update function. i will never go back to plain ubuntu after my experience with 11.
