Thnx for the suggestions

The main reason for wanting to install that distribution (Server version) is that I'm aiming to create a mirror of my Linode server.
Windows is a resource hog, and to be honest, I really want a fully Linux machine. I am tired of dealing with Microsoft, too much happening under the hood that I don't like. (I wish Win2000 was still supported, but that's not really relevant here.)
This laptop is basically a minimum capacity machine. I purchased it primarily for use on my catamaran that I live on. I use 12V deep cycle batteries and it's ideal for the environment. The existing Win7 Starter OS is already slow, and I fear that virtualising a linux machine on top of it will be unsatisfactory.
I don't mind having to do a bunch of manual steps to make things work, it's just that I haven't found a guide that actually works.
I'm considering borrowing/renting/buying a usb cd drive from the computer shop at the university where I'm studying so I can install from a CD.
Couple more questions:
If I install the desktop version (10.04), how much of a difference would it be? (From what I understand, it's the Server version that has issues being installed from a USB Drive.)
If I install Ubuntu 12.04, is that close enough?
Cheers,
