Alright, I'll have a look then.
I currently have Ubuntu on a DVD to help root my phone and I've already had a quick go.
Considering it was running off a slow DVD, it was very quick! And I found its pretty similar to OSX (and I've been using a mac for the last week, so it didn't feel too strange)
I'll come back after some more playing about on that DVD and after a look at the kde stuff :-P
