Um, you can't run windows software or install windows drivers on Linux anyway. You can run some software using wine (
www.winehq.com) but thats it. No fancy vxds or 'owt like that.
Generally, RPM distros have some problems with upgrades, especially if you've done much fine-tuning (in the actual system) since the original install. That's why source based distros suit me better. (Sourcerer, Gentoo, and Debian with source packages.)
Mandrake is nicer than RH IMO, especially for newbies as it sets up all the menus in an easy-to follow way. However, if you have learnt your way around a fair bit, I would suggest trying one of the other distros I mentioned. You'll get a better system out of it in the end, but you may have some trouble getting there to start with.
