So "Off the ball" with USB - Silly question

I need to get hold of a USB external HD for work.
The ones I've seen at good prices are all listed as USB 2.
All of the PC's here at work have USB 1 or USB 1.1 ports.
Will a USB 2 device work in a USB 1.x port, allbeit transfer at a slower rate or are they incompatible with each other?

Yep. USB 2 is backwards compatible with USB 1.1.

i second that :P

Thank you gentlemen.
Means I can get a USB 2 HD, the older machines will still run it and the two PC's with USB 2 ports in will run it better!
