Move over PlayStation 2. For those dreaming of a white-hot holiday gadget that doesn’t require a rain check, there’s Audrey by 3Com. WHAT IS IT? The Internet appliance is like a Palm Pilot for the Jetsons. A stylus accesses e-mail, Internet channels, a calendar, and an address book. Synchronize schedules through Pilot downloads — no excuses for not making it home for dinner. AUDREY fans Debra Messing and Kristin Davis gave them to the casts of Will & Grace and Sex and the City, respectively. ”It’s going to make organizing your home so much easier, simpler, and time efficient,” says Messing. PRICEY TAG White units go for $499; black, blue, yellow, or green costs $50 more. A not-so-small price for being organized.
