Yes there is a reason for "Mac funky gamma", which is that it results in colours on screen that closely reflect the actual image data ;-) - which is not only a nicety but actually of great importance in the print industry where colour mistakes have potential to be a serious and expensive issue. The print industry is one where the mac has had an historical dominance. Why would it benefit Apple to upset those customers? How many new customers would it get if it adopted uncorrected gamma as standard? Might it actually just end up with 2% market share instead? Richard's (conceivably mischievous) opinion that Apple should discard gamma correction seems to rest on the assumption that Mac Gamma is just a perverse nuisance that confers no benefit. I think that in the print industry at least it is perceived as a superior system to the 'oh who really cares about colour accuracy?' 'system' that's usual in windows and unix because that's 'good enough for the average office user or scientific programmer'. The PC/unix gamma is just what you get with no gamma correction at all, in other words the issue of display linearity is just ignored by those platforms. Back in the nineties I used to teach Photoshop. I recall one time a PC-using student brought in an image he'd scanned at home and was shocked to see how washed-out it looked on the Mac, saying it looked much darker on his PC. He seemed to suspect that there was "something wrong" with the Mac. So I showed him the histogram of the image, which turned out to contain no information whatever below about 20% brightness. On his system however this level had looked like black. Surely interoperability can be achieved without abolishing biodiversity? Isn't that supposed to be the intention of the Internet? Just because the great majority of users don't know what screen-gamma is or could care less, it does not follow that no manufacturer should offer a system designed for those who do. Let's not lose sight of the fact that the whole point of computers is precisely that they are tools that may be adapted to individual and minority requirements.
