Last year was supposed to be the year of the Ultrabook. It wasn't, and this year they aren't looking so hot either. Intel's answer to the MacBook Air was years late and several dollars too much to lure PC users away from their tablet fixation. Market forecasters IHS iSuppli, which had predicted more than 22 million of the uberthin ultralights would ship in 2012, later slashed that guesstimate to slightly over 10 million. Of course, the chipmaker says even thinner more powerful models are poised to make a strong showing in 2013. We say the odds are slim.
