21 hits and misses from CES

Of all of LG's demos, CNNMoney's David Goldman was most impressed with the company's Twin washing machine, which cleans two loads of laundry simultaneously.

"You put your biggest load of dirty laundry into the main washer, and below there's a separate, smaller washer that pulls out like a drawer for the second load," Goldman writes.

Doing laundry made a bit of a splash at CES this year. There was also a cool machine called Laundroid that folds your clothes.
