Whta does the knob on the front do? Obviously there is on and off, but does it then go on to vary the speed/power consumption of the drive? If not, maybe it should.

I'm not buying any new external HDs until 3.0 is up for sale, just doesn't make sense when it's a few months away.

Transfer speeds on 2.0 are way too low to support hundreds of gigs of data transfer, just filling half of that 2tb drive would take several hours.

@Iain: Technically speaking, the knobby thingy controls the glowiness of the glowy thingy.
