i enjoy using linux - using mostly Quanta and gimp.
i don't do everything and i know a little something about computers so i'm not exactly an "average" user.
most people are totally clueless about computers. so, yes, for them they need an OS which is so easy to use it is invisable.
the only OS that really fits that description is amiga/MorphOS. and that isn't quite "perfect", but at least it's not a horror.
looking forward to the day when it IS perfect. :-D
