U.S. networking solutions company TRENDnet has launched one of the world’s smallest wireless N USB adapters. The new 150Mbps Micro Wireless N USB (model TEW-648UBM) is uber small, measuring in at 0.59 x 0.74 x 0.28 inches (1.5 x 1.9 x 0.7 cm). I know what you are thinking – how can I possibly not lose a USB adapter so small? Well, when it's plugged into the side of a computer, it only extends out by 0.3 inches (0.8 cm) so you can easily just leave it in there. For laptop users, you can travel with the USB attached to your computer, without the concern of damaging the device.
