IMO the macbook at full brightness looks a tad bit washed out.
Thats simply the poor colour profile. download
Supercal and adjust the screen it makes a world of difference.
Both the macbook pro and the macbook come with awful 'color lcd' profiles that are just utter rubbish. That tool is a life saver for anyone wanting proper colour profiles.
As for glossy versus non-gloss. Well I have a macbook and a macbook pro.
The non glossy screen's benefit is simple. There's no glare and there is an even lighting across the screen. However it generally doesnt seem as vivid or bright as the macbook screen especially when your using less brightness to preserve battery life.
The macbook pro screen on half or quarter brightness is no way near as bright as a macbooks screen on the same setting. Strange but true.
On full brightness both when calibrated are much of a muchness.
The macbooks glossy screen does work well when playing dvd, or a movie in quicktime offering supperior contrast (or seeming to).
