We've been giving a fair amount of attention to Intel's Ultrabook concept, and if you've missed the coverage, the short and sweet of it is an Ultrabook is Intel's way of meshing the best parts of a tablet and an ultrathin notebook into a single device. Ultrabooks are designed to be thin, light, attractive, powerful, and full of features, and at least one talking head at Intel envisions Ultrabooks accounting for 40 percent of all notebooks by the end of 2012 (Intel as a whole is being a little more conservative). Where things get tricky is in the price. Intel wants Ultrabooks to cost consumers less than $1,000, and so far notebook vendors aren't hitting the mark. Can Intel's partners really sell Ultrabooks for under a grand?
