The interface is great. People have been raving (myself included) about the vast eye-candy upgrade Vista provides, but Ubuntu is not far behind. It takes a bit more of a Mac approach - simplicity - with subtle candy thrown in for good measure.
OK. Sometimes not so subtle - but from a Windows lad, it was just the ticket.
Everything runs from a "Start" bar at the top of the screen. Easy access pretty much to everything you need - as well a quite a nice holding bay for widgets and application shortcuts.
So. Onto the eye candy. Multiple workspaces - and when you switch to them - they rotate as if on a cube... Shoo. Wow. It's glitzy enough to be cool, but subtle enough to out-candy the Vista Alt-Tab shuffle.
It also has a funky feature called Window Wobble. This is definitely a little more playful (and utterly useless) than some of the othe features, but hey. How many times have you used the new WINDOW KEY-TAB in Vista? Really? Ask yourself... Any hoo. When you drag a window across the screen, it kind of bends in the direction you move it. And when you maximise - it does this jello-like wobble as it expands to fill the screen.
But at the end of the day. What's important? Windows is easy, and we all know it. This is where Linux is really starting to catch up - they've now got an easy, usable, pretty and "familiar" interface.
And if it can do THIS (with a couple of add-ons...). Well. Who the hell needs fancy Microsoft UI?!?
THAT'S the benefit of a world of geeks working on a platform just because it's not Microsoft. :)
