Summary: I've bought 4 of these so far and use them for customers who need an easy replacement wireless solution for their tower based computers. Easy install, strong signal. Integrates with Windows wireless connection configuration so you aren't stuck using a proprietary app for connecting to networks.
Summary: Stop shopping around and just buy it. It is only $13. Do not try to save $4 on the Edimax EW-7811Un. The Edimax EW-7811Un is limited to 1.5Mb/s and frequently drops the connection. Save yourself the trouble and just buy the Buffalo WLI-UC-GNHP. It works on XP/Vista/7/8/8.1 and Linux.
