I searched but didn't see this posted already. Frys.com has an Interlink Electronics VP6494 USB bluetooth adapter for $18 + tax - $15 rebate + free shipping, but it isn't in stock yet and will ship later. The rebate expires on 7/10/08. Basically if you want bluetooth on your cheap bluetooth-less laptop, just plug this little thingy into a USB port. It protrudes about a 1/4 inch (ie. barely noticeable).
