Besides the fact that CPUs are getting faster all the time, it's true that
color matching via ICC profiles is a heavy task.

Photoshop has been matching to the display is something meaninglessly close to real time for 5 years, and doing so on big files, not just on little JPEGs.

IE has done color-matching to the display for almost as long. I just don't buy the performance argument, particularly when we're talking about matrix transforms from assumed sRGB to monitor RGB. It just doesn't take that long.

I don't understand either. Maybe the problem is that every single widget, pulldown menu, application icon, and dock icon getting color managed is what would slow it down. But it's not like they need a high quality 16-bit precise conversion. Send them through 8-bits. I would think the processing power needed to rasterize a vector based language on the fly would be a lot higher.

I still think it would have made more sense to get "poor man's" color management by having deprecated gamma 1.8 and going with 2.2. That would have given Mac OS X users something loosely approximating sRGB, insofar as the randomly selected Windows machine loosely approximates sRGB. There would have been no performance hit for that.
