The Asus Zenbook UX21E is a new ultra-slim notebook by Asus, that fits into the new "Ultrabook" class of machines, to use a term coined by Intel. The Zenbook UX21E is an incredible 3mm thick at the front and 9mm at the rear and has spun metal and hairline aluminum for a strikingly sleek appearance. It's also built with Intel's new low-power Sandy Bridge Core i7 2677M mobile dual-core processor.
At first glance, the UX21 has an almost sterile appearance. Its brushed aluminum exterior could be mistaken for stainless steel. Upon closer inspection, there are some design queues here that are decidedly Asus and a few that are perhaps embellished upon from others. Apple zealots will immediately point to its Macbook Air-like traits but we'd offer those design similarities end at the simple dimensions of the system.
