First it was just 1.1 then it became 2.0 and now 3.0 is out. USB 3.0, that is.
Other than fast speeds which is expected, an interesting feature of the USB 3.0 is its ability to cut down it electricity portion all by itself when it detects a lack of usage.
Something like your monitor going to standby mode when there's no 'movement' for a certain period of time.
Now it's just a matter of when this would be a standard feature.
But don't start throwing away your USB 2.0 cables just yet, because the USB 3.0 is backward compatible with USB 2.0 ports. No idea if it works on USB 1.1 but if you are still using that, shame on you.
