You just trampled over "doesn't sacrifice performance for thinness". And using on my lap in a plane or whatever, like maybe I would when laying on my couch, was never even considered. Are you sure it's a practical measure to judge by a product and isn't just an Apple-tailored one?
No I didn't, I'm saying that if a laptop doesn't have an acceptable form factor, its performance (or even existence) doesn't matter. I'm also saying that models in the T series do not offer form factors suitable for everyone, contrary to the GP's claim, and offering the Macbook Air 11" as an example of the kind of form factor not offered.
