After numerous leaks, Lenovo tonight brought out its first halo notebook in years through the ThinkPad X1. The 13.3-inch system is the thinnest ThinkPad to date at no more than 0.83 inches but promises to trump the MacBook Air by overcoming the usual barriers in the class. A new generation of Lenovo's high-power, low-noise "owl wing" cooling fans lets it use full-power Core i3, i5, and i7 processors while still keeping up to five hours on its regular battery.
