Linux/BSD replacement fow WinXP for Newbie?
I need to bring a friend up to the latest clotting edge of OS technology. Years ago I got him to buy a used HP xw9300 workstation. It is monstrous but still running well, but time marches on. In the past I have seen commentards suggest Mint, but I don't know if that is still appropriate. So, any suggestions will be appreciated. My UNIX is quite rusty, its been 15 years ago since I touched it, so install needs to be fairly simple as I am 300 miles away from him and would be doing this over the phone.
Any ideas?
