Have an 8 year old emac, is it worth it to install and aircard? Updated to 10.5.8

Go for it. Need to know what model eMac you have. Some use an Apple Airport card while later models use an Airport Extreme card. You could also use the Wireless Adapter if you have USB 2.0. It would work on USB 1.1, but much slower.
