I've just upgraded to the latest version of Ubuntu Linux 7.04 nicknamed Feisty Fawn and I'm still very impressed by Ubuntu and the only thing keepeing me from using Linux only and dump Windows is that it's not possible to play Windows games on Linux yet...
I've got some more info on Ubuntu Linux in a previous post here:
Ubuntu Linux
Haven't tested the new release much yet but one thing I noticed is that it's much easier to use wireless networks now since everything is installed right away.
It's also possible to use both WEP and WPA now without installing any other drivers.
The layout is also much smoother and more "Windows Like", and it's also posible to change it in almost any way you want.
I haven't tested the new 3d desktop effects yet by the way...
Install and setup is very simple, so if you're able to install windows then you should have no problem installing Ubuntu since it's even easier than that.
If you haven't tried Linux before then I recommend you to start with this new release since I'm pretty sure you'll be quite impressed by how user friendly it is.
