I found it absolutely hilarious when it was done about 15 years ago. That was when we Apple users were pretty much the underdogs and expected the platform to die any day.
But now that Windows users feel threatened by Apple and are sensitive about this, it should probably be changed. Although it's a fun relic of the olden times.
Reminds me of how hugely offended some people were that the icon for a Windows PC in Mac OS X’s network browser was a blue screened monitor.
