D-Link has added to its compact 802.11n-compatible Wi-Fi adapters with its Wireless N 150 Pico Adapter (aka the DWA-121). The adapter can connect desktops or laptop Macs or Windows machines at up to six times the speed and three times the distance of a wireless 802.11g connection, and the incredibly small form factor -- about the size of a dime -- makes them easy to use in even the smallest USB hubs or USB ports without interfering with other peripheral connections.
