That's the problem isn't it "anyone who's ever used an Amiga". It's the same attitude that keeps Linux from being usable by anyone on the desktop, the developers and existing user are all used too it's fault and "know" what they need to do already.
New users are scorned and told to read the forums etc. It takes someone techy enough to get past all of that and start using it, by the time you've done so, you're one of those who already knows what extras you need.
i don't know where you are looking but I use Ubuntu and have been very well treated in the Ubuntu forums. and I don't have problems using it.
and, yes, it's WAAAAAAY more fun than windos
