Oh dear. The screen argument again.
Yes, the iPhone and the iPod Touch have amazing screens. As cellocello said, that is because the entirety of the device is screen. If their screens weren't perfect, we couldn't interact so well, nor be entertained quite so much - and we wouldn't buy the thing in the first place.
The MacBook... well I must say the MacBook update has really pissed me off somewhat. The prices for the new MacBooks in the UK have risen, including the White MacBook which remained the same price in the US but gained an inexplicable £18 over here.
The screen really has been a disappointment. No matter how I look at them they remind me of the old old old PowerBook screens of yore - contrast levels that could be only differentiated if you had a sheet of Pantone greyscale slides, colours that would change depending on whether you were at a 90 or 91º angle from the screen... okay well maybe they're not that bad but they are certainly much more poor than the previous generation (like mine).
To ppc750fx, you can have expectations for a laptop screen. They just shouldn't be based on desktop monitors. I have used quite a few laptops, both Apple and from other manufacturers, and I happen to believe that this most recent update has really cost the screens dearly.
