Ultrabook

We just got the brand-new ThinkPad X1 Nano and the chassis of Lenovo's new 13-inch Ultrabook leaves a great impression right away and is much more compact than the ThinkPad X1 Carbon. However, we are disappointed by the keyboard, because it reminds us of cheaper ThinkBook or IdeaPad laptops from Lenovo due to the reduced key travel.

Q1/2021 update. Early 2011 Intel started a new class of notebooks called Ultrabook that was definied primarily through a thin case, an energy-efficient Intel processor, long battery life, and a touchscreen display. Henceforth, Ultrabook became the moniker for all particularly portable laptops, and started somewhat of a race to design the thinnest case possible.
