Sorry, don't know if this may have already been posted before in the past, but I would be interested in you're opinions.
Personally, I believe that as soon as some form of "standard" distribution gets ironed out and more commercial suppoert picks up, it may perhaps be ready for the layman to use.
My friend isn't very computer literate and I set him up with Mandrake 9.0. Luckily, all he uses his PC for is to write papers for college (OpenOffice), download music (lime wire OR kazaa using WINE), and browsing the internet, in which he has a choice of Mozilla, Netscape, Konquer, and Opera. I got it all set up for him in about two hours, and he's been happy with it for the past 2 months!
