Networking specialist Trendnet recently announced what it claims is the world's smallest 150Mbps Micro Wireless N USB Adapter, the TEW-648UBM.
Boring name aside, this nifty device measures just 0.59 x 0.74 x 0.28 inches. Pop it into an open USB port and Trendnet says it will extend a mere 0.3 inches from the edge of your PC. For most people, the adapter should be small enough to keep permanently plugged into your notebook, even as you shove it into your laptop bag.
"The TEW-648UBM eliminates size constraints when using wireless adapters. On-the-go users no longer have to worry about leaving their adapter plugged into their laptop," stated Sonny Su, Technology Director for Trendnet. "As well, the addition of a WPS button makes it really easy to connect to WPS enabled routers and access points."
