Often overlooked in the upcoming switch to digital TV are the millions of portable TVs that will be worthless. Surprisingly few models are available with digital tuners like those now found commonly in large, flat-panel TVs.

A company called Eviant will introduce a range of portable models at next week's Consumer Electronics Show. The company hasn't disclosed prices, but a competitor already available at Radio Shack is pricey at $200.
