Slashdot's Timothy Lord is at the International Consumer Electronics Show (CES) in Las Vegas. There is no way any one person can take in the whole show. It's just too big for that. But on Timothy's first day, he spotted an overlay keyboard for the iPad that's been mentioned on Slashdot before, an invisible keyboard for your smartphone or tablet, and a crazy-interesting all-in-one computing device with a built-in projector and built-in virtual keyboard. Watch the video and join Timothy as he learns about these three devices. (Before you ask: Yes, we'll have more videos from CES over the next few days.)"
