Pre-orders for Apple’s upcoming Snow Leopard operating system topped Amazon.com’s bestseller list yesterday, knocking Windows 7 out of the chart just days after the online retail giant put Mac OS X 10.6 on its site. 
Late yesterday Snow Leopard and the Snow Leopard Family Pack were ranked number 1 and number 2, respectively, on Amazon’s software sales chart. The Family Pack provides licenses for five Macs.
Apple won’t release the new operating system until September, a fact that Amazon made sure to remind customers. "You may pre-order it now and we will deliver it to you when it arrives," Amazon said on the Snow Leopard sales pages.
Although Windows 7, also slated for a autumn release, had grabbed the lead spot on Amazon’s software bestseller list when two editions were heavily discounted during a two-week sale earlier this summer, Microsoft’s new OS was absent from the chart yesterday. The Apple rival’s best showing was heavily discounted Office Home and Student 2007, in at number three.
Apple announced Snow Leopard’s pricing nearly two months ago at its annual developers conference, when it said it would sell the OS for just IRs. 1,500 approx.
Snow Leopard was introduced in June 2008, when Apple touted it as a performance and stability update that would "take a break" from major new features.
The Snow Leopard upgrade requires an Intel-based Mac and Mac OS X 10.5, aka Leopard; users running Mac OS X 10.4, known as Tiger, must instead purchase the more expensive "Mac Box Set," which Amazon is also selling as a pre-order. Text from pcworld.in
