There is no such thing as too small or too large in the displays.
I used a 17 Inch MacBook pro, 13 Inch White Polycarbonate MacBook, 11.6 Inch MacBook Air and I can say that there is no such thing as too small and too large when we're talking about consumer tasks (without XCODE, Dreamweaver, After Effects, Final Cut, ETC.). You will eventually adapt to it. It just looks small or big at the first few days. But after that, it will appear perfect. Apple made sure it goes that way, so no customers of theirs would complain about screen size. However, prejudice people are.
