In any case, the higher-level abstractions always seem to win out in the long run. It happened with Quartz, Cocoa Bindings and even as far back as C versus assembly. So while you may not use it right away, you almost certainly will eventually.

I definitely agree. To stay with the above example, I find it highly improbable that a garbage-collected build of Delicious Libary would run any slower on the machines that will ship around 10.5's release than it does on today's high-end hardware.
