Yes, I wrote pretty much exactly this in another reply in this thread. The main problem is that "thinner" costs a lot in terms of other features and functionality, and yet there is a whole class of users for whom "thinner" has no value whatsoever. That's me. Stop trying to make it thinner and pleasing us becomes easy.
i think it’s high time apple decouple screen size, core-count and thinness with “pro-ness”
there is no technical reason (that i know of) stopping apple from selling a 15 inch laptop as thin as the macbook air (and still even get a low-clocked 4 core cpu in there)... i for one would buy that up in a heartbeat
for those that really need power, they can have a much thicker 6 or 8 or higher core cpu + discrete gpu and it would be fine (for that target) i would imagine...
but maybe apples marketing dept knows more than i do (not being sarcastic)
