Nintendo 3DS, $170
How is this for a hot toy? Justin Bieber just endorsed this hand-held system in his new “All I Want for Christmas is You” video with Mariah Carey (the Biebs and his crew spot the gadget at the mall and are seriously impressed). Nintendo’s latest update to the DS sports 3D graphics (no glasses needed) and has a host of new games at about $20 to $50 a pop. But at nearly $200, plus the cost of games, let’s just say you might have to have a few hit singles of your own to find the cash for this one.
