One of the best-selling smart phones in the world was at the show, but chances are you'll never be able to buy it. Motorola was showing off its Ming, a Linux device that is selling like hot cakes in China and was recently introduced in Brazil.

The phone has a clamshell design that, when folded, is about half the height and width of the Motorola Q, which is pretty svelte in its own right. The touch-screen is surprisingly bright, it has strong media capabilities and a lot of the standard smart phone features, such as syncing with desktop data. It also employs handwriting recognition, which turns notes you write on the screen with a stylus into digital text.

I was told it's remotely possible the Ming will appear in the U.S., but so far no carrier has expressed interest, a person in Motorola's booth told me. If that changes, the Ming could be a big seller here, too.

Bottom line: The Ming could be a big hit in the U.S. if Motorola decides to sell it here.
