NPD: Apple’s Mac OS X Leopard launch its best ever
Monday, December 17, 2007 - 04:14 PM ESTThe launch of Apple Inc's latest operating system, Mac OS X 10.5 Leopard, was its best ever, NPD Group said on Monday.
"When comparing the first full month of sales of Apple Mac OS 10.5 'Leopard' (November 2007) to the first full month of sales for Mac OS 10.4 'Tiger' (May 2005), dollar volume for Leopard was up 32.8 percent and unit volume up 20.5 percent, NPD Group Inc said in a statement," Duncan Martell reports for Reuters.
"The new version of Apple's OS X software costs $129 for a single user and $199 for a 'family pack' that can be installed on as many as five computers in a single household," Martell reports.
"Leopard is the sixth version in as many years, a fact the Cupertino, California-based concern is quick to contrast with Microsoft Corp, which went more than five years between new versions of its Windows operating system," Martell reports.

Let me save you whiners the time: "Apple is not releasing full new versions every year, so you can't compare it to Vista's release." Wah, cry me a freakin' river.
