I have been using ubuntu since 7.04 and 10.10 is the best so far, with 10.10 I don't even run windows anymore by the way windows xp 64bit is the best windows.
I tried ububtu 11.10 several times but it would crash after a month or so and the same with kubuntu 11.10 so I am waiting for 12.04 and I hope it will be great and not crash.
However I don't want to search for something when I know where it is and what it is I want a menu or an icon at my cursor to click on and get there very quickly and I don't want to talk or touch the computer, I want applications that are known to work and work well.
The only problem I have had with 10.10 is that I cannot get it to OCR mixed content well I keep 10.10 on my portable drive as backup and I try the new systems on my internal drive I hope 12.04 works well and that I can configure it to my licking.
