Here’s a novel idea: a USB gadget that’s actually useful!
I’d understand if you read this and thought “oh great, another worthless USB powered gimmick”. It seems that you can get everything from USB powered hamburger flash drives to miniature USB powered aquariums. Most of the “USB powered” stuff is just plain useless, though.
That’s why when I saw this USB hub combined with a letter opener, I thought it was pretty cool since it’s somewhat useful. The (albeit cheap looking) plastic box contains a four-port USB hub, digital clock, and a motorized slot that will cut envelopes open. You can power the letter opener from the USB connection or 3AA batteries if you’re so inclined.
Get the USB hub with built-in clock and letter opener for $15.
