i experiment with ubuntu and i don't find anything, so far, to be difficult. unless i have to get into the terminal and start changing things, then i get lost sometimes. the forums are easy to follow, i really haven't needed to go to them that much. the only things i haven't found yet are two small items. i can't find a tv tuner set-up like windows media center and my sound doesn't seem as clear. i've got all the graphics going i can find in a basic set up. no beryl themes will install, though.
if you do basic surfing, or check email, etc. this is a pretty good operating system. i'm trying to talk a few people into installing it because their pirated versions of xp is horrible. so far everything has worked, even my ati drivers. im going to download some music from jamendo to see how well it works and how it files everything.
