Here’s another double-duty hub. The 2.0 USB 3-Port Hub comes with a calculator. It also has a built-in thermometer, a 12/24 hour World Clock, a calendar, an alarm, timer, and time announce. The device supports Windows 2000/XP/Vista and, at a size of 180 x 99 x 22mm and a weight of 149g, the hub comes with its own cable at a price of $19.00. Now that we think about it, it is more like quadruple-duty.
