Apple claimed that the main reason for the Leopard delay was due to the diversion of OS X programmers bought over to help out with the development of the iPhone. After seeing the screenshots of Leopard (in it's current state) it couldn't be more obvious that Apple was being quite truthful But which OS X programmers were bused over to the iPhone lab? I think I have an idea who some of them must of been. It looks like every last member of the lickable UI team for OS X got iPhone duty: The first shot below is just one of the iPhone screens, with it's beautifully rendered and aqua-esq buttons and controls. Colorful, mouth-watering, lickable buttons that look like someone actually sweated over the design details until they were nothing less than perfect. The next shot is what you're getting with Leopard. Whoever is working over at the iPhone lab - please come back.
