it's not that apple "doesn't do this." it's that apple had a recent "ground zero event," a term i just made up, which means they had a perfect opportunity to ditch all their old APIs and start anew when they switched operating systems, from macos "classic" to macosx. that was in 2001, which is pretty darned recent. most new mac apps are written to the cocoa api, which didn't even exist before macosx.

however, microsoft is slated to do the exact same thing with the next version of windows, which will supposedly break binary compatibility with old windows apps. if ms has the guts to follow through on this, it will be a Very Good Thing.
