Apple has delayed Leopard because they have decided to allow apps built in Xcode to run on the iPhone.

Yeah. I was wondering if there was going to be any wailing and pulling of hair and gnashing of teeth. Oh, BTW, I've got an app, or, well, a half-made demo of same that I might possibly have ready for the meeting, but I'm still unsure. (Which is why I haven't mentioned it before)
