I've got a few Linux machines around, the fastest is a Celeron 440 with a gig of RAM which runs Xubuntu, it has its flaws here and there but all in all it does everything you want except gaming, installation nowadays is easier than Windows, I've used several versions and varieties of Ubuntu, Fedora and OpenSuse on a whole bunch of Intel and AMD machines and they all installed the correct drivers and so on.
Also there are several lightweight distro's around which can turn an old Pentium II with 128 Mb RAM and a 2 Gb HDD into something useful.
The only hickup is when something isn't working, that will mean you'll have to dig for answers online and use the terminal to type in commands, some people could be a little intimidated by that.
