So let me get this the display on a unibody MacBook is worse than a cheap
Netbook, somehow I find that hard to believe.
Believe it. It is. I had both showing the same online video feed today whilst watching the Malaysian Grand Prix. The quality of image on the Netbooks screen was more easily visible from more angles than the Macbook. Literally, 5, 10 degrees off perfect, and I couldn't read the macbook screen. It's PATHETIC.
Apple charge premium price, but use bargain basement components.
Oh - and good luck with the DL-DVI adaptor you'll need to make the most of an external display - it's barely fit for purpose.
As a Mac user (specifically for the abilities of Keynote) - I refuse to recommend Mac's to others.
