Asus Zenbook UX21 teardown

Asus Zenbook UX21 teardown

ntIn late 2011, Asus launched their Zenbook series of Ultrabooks. These super-thin notebooks, offer more processing power than netbooks, but weigh less than traditional laptops.

n

ntThey are designed to be a Windows alternative to Apple’s MacBook Air. Hewlett-Packard, Dell, Acer, Asus, and Toshiba are all jumping on the Ultrabook bandwagon (thanks in part to a significant push from Intel).
nt
ntAs of this writing, the Zenbook is available in 11-inch (UX21) and 13-inch (UX31) models and a variety of hardware configurations. Follow along as I crack open the 11-inch Asus Zenbook UX21.
nt
ntFor a detailed analysis of the teardown, check out my article and video, Zenbook teardown: Blatant copy of MacBook Air.
