Why USB 2.0 instead of 3.0?

Because of costs. The Atom chipsets don't support USB 3.0 natively. So vendors would have to add NEC/VIA chips to offer USB 3.0. And since Chromebooks will be mostly working with WiFi, it won't matter much.

No relation to chrome os but I've had trouble with usb 3.0 drivers for Linux. I had installation problems with Ubuntu, Fedora and Mint when I had anything plugged in to my 3.0 port; remove the device and all releases installed OK. I don't have any 3.0 devices but all of my 2.0 components work fine in the 3.0 port after the install.

Thanks, those answers make sense.

yah, 3.0 would be better.

Usb 3.0

What is the difference between 3.0 and 2.0?

3.0 is MUCH faster than 2.0 for data transfers.

Will there be USB Chrome software support for, say, a data stick or an external mouse or a printer?

Cr-48 already reads SD and MicroSD cards as well as USB thumb drives. Various users have connected USB mice & keyboards to their Cr-48s. Printers (due to the nearly infinite number of drivers) currently rely on "cloud print technology."
