CodePoetry and a bunch of others are pointing at this very long and interesting rant about developing for the Mac, by drunkenbatman.

It’s way too long to justify quoting any part of it; if you’re developing for the Mac, you must go read it (and the comments, too). I disagree with some of the conclusions – especially regarding Java and .NET – and the style is a little grating; I for one wouldn’t use slang like “prolly” outside of an informal e-mail or chat. Still, very recommended.
