There are plenty of preferably laptop designs on the market, the problem is that they do not run OS X.
Or, at least, when I left OS X, it was just as clunky & crashy & inconsistent as everything else. And I realized that all my tools ran elsewhere or I could find decent alternatives.
I got really tired of limiting myself to the Apple silo. IMO, Apple's only thing was that they were nearly perfect, and that was reason to accept lock-in. Now, not so much.
