I am a huge Ubuntu fan! I have it on an external USB HD so I can plug it in and run it on any PC!
There is actually a ton of great software at your finger tips! Just go up to the "Applications" tab and at the bottom you should find "Ubuntu Software Center"
You can browse through tons of software and install it with a click of the mouse. I highly recommend Wine. It will allow you to run windows apps within ubuntu.
Anyway I am still very Nubish to Ubuntu, but I am with ya I think its an absolutely awesome OS, I haven't played much with the desktop version, but I have been running the server in shell with webmin for some time.
