I'm trying to find a lite weight Linux distro for one of the computers in our office. Its has an AMD Athlon 2.1ghz with 480MB of RAM, and with XP Pro on it, its so sluggish. We don't use it for much - all it has to do is access the web, load pdf & maybe tiff files, and be able to access our networked server, with an easy to use GUI desktop. Not asking much right . I have used Ubuntu some, but still a Linux noob, so I was hoping someone had some good ideas for a distro. Thanks.
