Last year, I questioned Apple's aesthetic judgment, regarding their choice of pink as a color for the new iDisk icon, with the switch from .Mac to MobileMe. Well it seems like someone at Apple is listening (to good sense, if perhaps not to me personally).
With the release of 10.5.8 earlier this month, the iDisk icon has switched to a far more attractive shade of blue. Now if we can just get rid of the hideous pink-stars default desktop, we really will be getting somewhere.
It's a minor point, but I have to add that the new blue iDisk icon was predicted by this blog in a mockup we produced way back in April.
