It may be the heat getting to us, but this USB Clock Hub seems like a decent proposition. You’ve got a hub—useful—and a clock—don’t want to be late—all in one. Together at last for $17.
The only problem is the spacing of the USB ports. You won’t be able to fit 3 USB sticks in simultaneously. Three standard USB plugs should be fine.
