I didn't actually /want/ a 15", previously I'd always used T4x and T4xx, but the specs are not possible on the existing 14". The specs outweigh the form factor for me by far. It is usable on an airplane. Weight doesn't bother me at all, and it's not heavy or thick. But I'd buy a 14" if I could get the same specs.
