Yeah, finally: slashdot recognizes the idea of self-contained applications. RISC OS always had them, NeXT had them, Mac OS X has them, linux doesn't. Some ex RISC OS people are trying their best with ROX to bring the usability of RISC OS onto the linux platform. While being around for a long time, I always thought linux people never get it. But maybe there's hope, and finally we will see self contained applications instead of binaries and stuff all spread over /usr/local/bin /etc /lib /bla. Not that I really count on it, I'm save with Mac OS X which does a decent job of making applications self contained and organizing preferences and additions in a decent directory structure.
One thing I'm still missing in the Mac OS X application bundle system is accessing the application's help without starting it. Its in the bundle, but finder has no generalized way of accessing it. Pity.
