OS X 10.6 Snow Leopard for Mac and iPhone?

We already knew that Apple's next computer operating system, OS X 10.6 Snow Leopard (estimated for delivery mid-2009) was leveraging some of the amazing work done by the iPhone team, including the highly optimized QuickTime X. Now Apple Insider brings word that things like CoreLocation and more Multi-Touch might be making their way back to the big desktop brother as well:

CoreLocation will utilize a Mac's existing networking hardware to triangulate the system's location in a manner similar to the way the original iPhone was able to use the technology to emulate a true global positioning signal. [...] Snow Leopard will also gain access to a new set of Cocoa-based programing interfaces for leveraging the multi-touch features of the latest MacBooks and MacBook Pros within their applications.

The synergy between Apple's desktop and mobile OS X development really seems to not only be benefitting both platforms, and optimizing R&D's bottom-line, but bouncing off each other in iterative splendor. Hopefully iPhone OS 3.0 can take a little back as well -- I'm looking at you universal spotlight search!
