The Apple Online store has officially offered a release date of August 28th 2009 for OS X Snow Leopard, an OS that was originally set for a September release date. The new OS has promised extra functionality along with improvements to such popular Mac apps as Time Machine and the Finder App.

The upgrade cost is a mere $29 and comes with free shipping, while Mac families can pick up a five license package for only $49 with free shipping. The current upgrade requires an Intel-based Mac device, at least 1GB RAM and 5GB Storage space.

So what does the upgrade offer? How about 64-bit compatibility, faster overall processing, 7GB less space than Leopard and even Microsoft Exchange support for all your business email needs. [via Apple]
