i got one of these a while ago - the free netbook i got came w/ a 54mbps b/g card. this thing makes it go sooo much faster.
the one i got was a refurbished netgear piece. this one is much smaller - i dont know which would be better i'm trying to decide if i should waste $10 or no
anyway i've seen these around theyre usually more like $30
