When comparing mid level ultrabook, I looked at many models/brands, which includes ASUS, Lenovo, Sony, DELL, HP, and ACER (there are several that I compared, can't remember all models num. now) Of course, macbook air as well, but it is too expensive so can't count as mid level ultrabook (basically, looking for an affordable ultrabook without sacrificing performance too much.) And a price tag around 600. This one comes out on top. Overall this is a great touch screen laptop.
