Here's the VOIP Accessory for the gadget lover in your house: The Sony VAIO VOIP Mouse. What makes it so special? It's an optical mouse, a VOIP handset and a speaker phone in one. Pick it up to make a call; put it down again to use it like a speaker. Like many new gadgets, however, it doesn't come cheap. Expect to pay at least $100 for it online.
