an almost painless linux
you might want to give simply mepis a try for a pretty painless and usefull install of linux. It's a free download, (liveCD with installer) and comes with a good deal of usefull sofware. I have a server and a laptop running it, and have no complaints. I still prefer the amigaOS [real or emulated] to any other.
I also have to use XP and Vista daily. I think that linux is much better than windows and that Open Office is very close to MS Office.
