Pros: can use on multiple computers
Cons: Installation is not easy on windows
As a linux user primarily, I had had limited luck with similar items from Medialink, D-link and Ralink. This one, which uses the Atheros guts, is the most linux friendly of the bunch, and also works great with Windows 7. At last I can use my desktop with wireless that just plain works, regardless of which version of linux I use. To be frank, there are some linuxes that still don't work with it, but they are now the minority. All the big name distributions work flawlessly with this, and with linux getting better and better on a daily basis, this will only improve. No drivers to install... (unlike windows) just plug it in and it sees your available connection(s). Now that's what "plug and play" should be... not plug, insert cd, wait a few minutes, reboot, THEN (maybe) play.
