Why not just drop support for OS/X altogether?
The recession and Windows 7 will kill it off anyway. And for those who prefer Unix, just switch to Linux. All the files are where you expect them to be, you don't have to wait for your favourite software to be ported to Fink and Firefox is updated automatically through the package manager. That's what's in store for my (foolishly purchased) Mac Mini as soon as Apple stops supporting 10.4.
