One can never have too many USB ports, and the Satechi 10-Port USB 3.O hub (On sale for $59.99, usualy $69.99) certainly is welcome in my office. It looks like a power strip, but it's really a mighty USB hub. Because it is such a gathering spot, I call mine the hub Pub.
The unit has 9 regular USB 3.0 ports plus a port located on the end of the hub for iPad charging. This enables you to be connected to USB devices and your portable computer all at the same time from a single hub. The 10th port also features an On/Off switch.
