LG on Tuesday claimed a design breakthrough for notebooks with an addition to the Xnote line that could hint at future plans for ultraportables like the MacBook Air. The P210 has a 12.5-inch display but, through a new extra-thin bezel technology, is no bigger than a typical 11.6-inch notebook. Simultaneously, it has much more performance than alternatives with an ultra-low voltage 1.33GHz Core i5 that can Turbo Boost to 1.86GHz.
