Lenovo's decision to back out on the ThinkPad X301 may have just been a temporary measure as a pair of Swiss stores have prematurely shown a sequel built more consciously to take on the new MacBook Air. Billed as the ThinkPad X1, it would switch to a 160GB solid-state state drive to slim down to about 0.85 inches at its thickest point. The system would try to bring over Lenovo's reputation for strong designs by making its 13.3-inch display cover out of jab- and scratch-resistant Gorilla Glass.
