I have had Luna as my main OS on a cheap netbook for a couple of months. I like it a lot. The (G)UI is clean and streamlined. I much prefer it to Ubuntu Unity. It's similar to OSX in many ways, which is not a bad thing.<p>And it's much faster and smoother than Win 8 on the netbook.
How's the battery backup?<p>Low battery time(even after using laptop-tools) is the thing I hate about ubuntu(and linux) on laptop.<p>Windows 8 is amazingly energy efficient.
