A fridge that sports a docking station just might be the coolest kitchen innovation at CES this year. Whirlpool’s Centralpark connections refrigerator is 270 pounds of stainless steel that does more than keep food cold. You can dock a tablet PC, digital photo frame or even an iPod stereo system to the door. Maybe next year I’ll see a fridge that can also tell me when my leftover casserole is going bad. Or one that knows when I’m low on milk and can generate a grocery list for me.
