twophat: Just wondering about what peoples preferences were GNOME or KDE? and any reasoning behind their choice
KDE 4 is your choice :)
foobar: KDE offers a lot of options. Many people like that, some find it a tad confusing. Gnome tends to choose a few ways of doing things for you. So, at first glance it's simpler. Personally, I use Gnome, because I like the simplicity. It does all I need from a desktop and with Ubuntu it is all well integrated and tested. But there are some distros that focus on KDE and you will probably find the same good level of integration there then.
In the end, it's all a matter of taste. Don't listen to those who tell you that one is better than the other. They both have advantages and disadvantages, and some things that will hit your personal preference and some things that will not.
Here's an idea: Get the Ubuntu and the Kubuntu Live-CD and try them both for a bit and see which one you like.
