Definitely a problem on the 15-inch - you're stuck with either running at native resolution with everything far too big, or running at Apple's suggested resolution with noticeably soft display and visible artefacts from the scaling - at least to me.
(I ran mine at maximum 1920x1200@2x, because if you're going to have scaling artefacts you might as well get the screen space in return)
