I must respectfully disagree to some extent with veribaka. In my opinion, Fedora IS good - but to veribaka's point, I think, it is not the distribution you probably need to fulfill your requirements, if "light" and "fast" are primary considerations. Fedora is a rather full-featured distro, and as such, it requires more and better hardware to achieve good performance that the lighter distros suggested. I run Fedora (versions 4,5,7, and 8) on a variety of systems including servers, desktops, and laptops, mostly older hardware. I'm happy with its features and performance, for the most part, but I don't do a lot of really intensive stuff with it, so I'm probably not the best judge of performance. I'm posting this reply using Fedora 8 on a Pentium III laptop with 512Mb of RAM, and while it's satisfactory for surfing the Net and other general-purpose type stuff, I don't think I'd try gaming or 3-D rendering with this particular box

FWIW, from what I've read and experienced, if you're gonna run a graphical interface on Linux, give it as much RAM as you can - Linux likes RAM!
