You knew they were coming, but today it's time to choose -- will you withstand the temptation of a tricked-out ThinkPad W520 workstation or T420s thin-and-light with Sandy Bridge CPUs? Yes, Lenovo's rolling out the red eraserheads this month for Intel's new chips as fast as it possibly can, with these latest two models hot on the heels of the ThinkPad T420 and T520 and ThinkPad Edge E420s. The $1,199 14-inch T420s distinguishes itself with slightly slimmer construction, a 1600 x 900 resolution and a 2.5GHz Core i5-2520M CPU in a package that weighs less than four pounds -- strangely, there's no Core i7 or discrete graphics here -- while the $1,449 W520 workstation comes standard with a 2.7GHz Core i7-2620M chip and an NVIDIA Quadro 1000M GPU with Optimus graphics-switching tech. Of course, the W520 base configuration comes with only a 15.6-inch, 1366 x 768 screen, but don't you fret -- an additional cash infusion can get you a 1600 x 900 or even a full 1080p display to render your video with. Go ahead, spec them out to your heart's content, while we wait for an even more groundbreaking rig to drop from the ThinkPad heavens.
