John Siracusa on what Apple should do this year. Most of these are obvious, but critical nevertheless.
Small Aside: It strikes me as odd that the 13” Retina MacBook Pro performs as poorly as it does. My MacBook Air’s integrated graphics power a display of nearly identical resolution to the MacBook Pro’s in a significantly smoother way. My display has a vertical height of 1,440 pixels, whereas the laptop’s display is 1,600 pixels vertically. It’s surprising that there’s such a significant performance difference in that 2,560 × 160 pixel area.
