"After showing off Mac OS X 10.6 "Snow Leopard" at last year's WWDC, Apple is finally ready to ship it out the door this coming September, for a quite reasonable upgrade fee of $29 for Leopard users (as opposed to the regular $129 for larger refreshes). While the added feature list is relatively slim, and there are few surprises between what was confirmed last year and the various leaks from developer previews, Apple's still giving users and developers some fun new tech to play with -- particularly the GPU-exploiting OpenCL, and the GrandCentral tech for developers to ease application optimization for multi-core processors. Pretty nerdy stuff, but if it makes our Dashboard Sudoku Widgets run faster, we can hardly complain. Other updates to the OS Apple is trotting out at WWDC:
* Apple rewrote the Finder, while keeping it mostly the same on the surface, for a bunch of "little benefits."
* There's built-in Microsoft Exchange support in the OS, including Mail, Calendar and Address Book syncing.
* QuickTime X has a new "modern foundation," HTTP streaming and a whole new look. Users can record and trim video, and upload to sharing sites like MobileMe and YouTube.
* Snow Leopard has half the footprint of Leopard, amounting to 6GB in savings and 45% faster installs.
* New trackpads can handle handwriting recognition now, and there's new text selection "AI."
* All core apps are 64-bit, and performance improvements abound. Mail boasts 85% faster message loads and 90% faster loads, while Time Machine has a 50% faster initial backup time."
