For weeks now, Lenovo aficionados have been salivating. Thanks to a series of leaks, more than a few of you have been awaiting the ThinkPad X1, the skinny, girlfriend-proof follow-up to the company’s vaunted X series. One problem: it didn’t officially exist. Well, the jig is up, and the X1 is at last a real, whirring product, on sale tomorrow with a starting price of $1,349. As expected, it marries that iconic red nub and rock-solid construction with some flourishes you haven’t yet seen on a ThinkPad, including a 13.3-inch Gorilla Glass display, integrated, fast-charging battery, and a buttonless trackpad. And, as you may have gathered from those leaked shots, it’s the slimmest ThinkPad yet, measuring just 16.5mm (0.65 inches) at its thinnest point.
