I have 3 Linksys WRT54Gs, about to buy 2 more.

NAS is a big expensive box with hard drives, and another copy of Windows. It adds network storage. It's for people who want a plug and play solution. People who have a toolkit consisting of two screwdrivers and a pair of pliers. From the 7-11.

For those of us who pop the hood and fiddle all about, just get a big hard drive and add it to a computer that is always on. Share the hard drive. Does the same thing. Bill Gates doesn't need the money.
