Cross dev with GDC is possible as long as you don't use block, that is, as long as you use only 'dispatch_xxx_f' functions, but you lose some of the GDC advantages.

True. But blocks + dispatch_xxx are the killer combination.

You can get many of the same advantages using NSOperation, and write code that runs on Mac OS X 10.5 and 10.6 (and iPhone). Your code will automatically take advantage of GCD on Snow Leopard, since NSOperation is built atop it.

A good general rule is to write to the highest-level API possible to express your intent as richly as possible, and drop down to lower- level APIs when measurement shows it to be necessary for performance.
