‘HDR mobile computing’ is how I would neatly define the Ultrabook category. These surprisingly powerful laptops can work as efficiently as a netbook and then when you need the power, kick-in cores, turbo and other special features to give you a truly all-round solution that includes video editing, gaming and care-free desktop-style working. The Asus UX21 is one of the lightest, smallest and yet, most powerful of the Ultrabooks, at least in the Core i7 1.8Ghz version we have here. We’re impressed with what’s inside and with its weight and style but there are a couple of potential showstoppers for some people. Read-on to find out more in our detailed multimedia review of the ASUS Zenbook UX21E. Thanks ASUS Germany for the review sample.
