Pretty much 
every year, a big trend emerges from the Consumer Electronics Show. And pretty much every year, it’s heralded — at least for a short while — as the next big thing in consumer electronics.

Two years 
ago, 3D TV commanded center stage at the annual Consumer Electronics Show. Last year, it was tablets. This year, while both of those product groups will still be shown in force, it looks like the PC is ready to make a comeback.
The computer industry, which seems swept by one revolution after another, is back in the spotlight at CES this week, with a new version of Windows and a new type of laptop heralding the new era.
