Combine a mouse pad with a USB 1.1, 4 port hub and you have a very useful tool. With its dual speakers, you can connect it to your iPod, MP3 or MP4 player. Roll the pad up to save space (or if your current mouse is infrared.) At a size of 280 x 220 x 40mm and a weight of 190g, the device has an on/off button and volume control, and comes with USB and 3.5mm audio cable for $22.00.
