i didn't mean to be negative in that last post of mine there,
i would say mandrake, red hat and probably suse, are at least as easy to use as windows.
Installation, of the system and of programs, is however a bit harder than windows.
This is fine if you are just a user of a system, but if you own the machine, you will probably be system admin as well, ie you must keep your own config files up to date and know how to install and uninstall stuff.
Luckily there's a lot of easy to use documentation about system admin of linux and GNU, so if you can be arsed to look something up whenever there's an admin job to be done, then you're good to go. In that case you may as well get one of the major distros since the actual user part is a lot more stable than windows, and as i say is as easy to use.
If you buy a licence from a main vendor like red hat or mandrake, you can be entitled to all sorts of tech support as well, for added benefit if you are having problems with the system admin part...
