Looks like the latest version of Mac OS X 10.6 Snow Leopard might just have gone Gold Master according to Apple Insider, leading to expectation -- and anticipation -- of a shipping date as soon as a few weeks from now.
Now, TiPb covers Apple news in general only so far as Apple's 360 degree business model tightly integrates all their offerings and what happens in one product generally either involves or at least touches on many others, including the iPhone. However, following Snow Leopard as we have, it's interesting to see how Mac OS X was originally stripped down to create the core of iPhone OS X, and now many of the iPhone's innovations, like QuickTime X and built-in Exchange ActiveSync support are being leveraged back into the Mac -- not to mention the whole OS being smaller and tighter. Likewise, iPhone 3.0 has benefitted from data detectors, while Mobile Safari is out pacing it's big desktop brother in HTML 5 support.
Snow Leopard promises some great new technologies we likely won't need on the iPhone for a while, like Grand Central's packetizing of processes to hit multiple cores, but OpenCL, which lets GPU's be used like CPU's for general purpose computing could really leverage that new PowerVR SGX chip in the iPhone...
Mac doesn't get free OS updates like the iPhone, but at $29 for a single user and $49 for a 5-user family pack, Apple is putting on the pricing pressure.
And hopefully there'll be some more iPhone-involved surprises in the roadmap. (64-bit Cocoa iTunes anyone? And dare we ask again for Mobile iChat?!)
