Is SP3 the best piece of engineering of all mobile devices?

I mean: Core i7 (Haswell) in 9 mm, 23-150 kickstand, thin optical stack, cooling system, active pen, unibody design.

A lot of tech people with whom I talked about it, said SP3 is not for them BUT it's probably the best tablet/hybrid ever made engineering wise.

What's the competition? MBA? iPad Air?
