All this is very off topic I guess, but meh, what the hell.
I used to be VERY into redhat (back in Redhat 6.x days anyway
) but moved over to Debian around 2003. I've been using Debian, and Debian based *nix's ever since, and although I'm too much of a geek to use *buntu (I prefer Xubuntu over them all, very light initially, and being a Deb based system, very customisable) I have to say it is one of the most user friendly *nix distro's out there, that does not force a user to have loads of crap that they wont ever use, ala Mandriva or Fedora.
It comes with what you need for a desktop, or server, depending on the cd you order/dl, and it does not try to stop you modding things either, Mandrake 10 drove me nuts with the way it re-wrote certain config files every reboot.
Oh, and as for the Wifi card support in Linux, ever heard of
ndiswapper?
