Space saver. A new device combines a touch pad and a tablet that lets you use your finger as a stylus. VersaPad, made by Interlink Electronics (800-340-1331), offers a programmable five-key tool bar for one-touch response. This way, you can sign your name or create a graphic image on the tablet and then cut and paste it so that it appears on your document. Cost: $69.95 if you buy the VersaPad directly from Interlink, or save $20 to $30 by getting it at Circuit City, Costco or other retailers.
