If you have an older Mac or PC that wasn’t blessed with the latest N wireless technology, this $50 adapter is for you. Just run the software and plug it in. A separate base is provided for desktop models. I tried this unit out on my wife’s aging MacBook and it was blazingly fast. The only glitch is that you have to remember to turn off your Airport and use the provided software, which works well. VIsit: http://www.macsales.com
