Yup, after a full day of releases in the Apple world yesterday, today is all about Ubuntu, with Ubuntu 11.10 released by Canonical. If you haven't had a chance to hear about this, check out the tour (which by the way, is about the coolest thing I've ever seen, a full HTML5 (I assume) UI of the Ubuntu desktop... wow. Check out what happens when you install an application in the software center).
Check out the full desktop features here.
Not a huge amount else to say, download, install and enjoy. That's what I'm going to be doing tonight after work (or to be safer, this weekend when I'll have time to un-break anything that messes up as this is my work machine) :)
Huge congrats to the Ubuntu team!
