Acer isn't kidding when they describe the $1699, S7-391 ultraportable as cutting edge. This Windows 8 laptop is so thin (11.9 mm) and stiff, it could double as a weapon in the wrong hands. Did I say wrong hands? Assuming you can afford it, there are no wrong hands for this laptop. It's forward thinking in its design, eye-catchingly attractive, travels light, and is a heck of a performer.
