When we announced Tiger [Mac OS X 10.4], there were 15 million units that were eligible to run Tiger and we did $100 million of revenue on Tiger at the first quarter of launch."
If Leopard sells to current Mac owners at the same rate, Apple will collect about $140 million in revenues during the current quarter, he added. However, Gottheil came up with his projection by looking at the current installed base of eligible machines and comparing it to what existed when Tiger, debuted in April 2005, notes [url=http://macworld.co.uk/mac/news/index.cfm?newsid=19467]Macworld UK[/url].
"It really is a function of the installed base," said Chris Swenson, analyst with the NPD Group. "Each upgrade sold better than the previous one, which is pretty impressive. The first two months after Tiger was launched, it ran 30 per cent higher [in sales volume] than Mac OS X 10.3, and more than twice as high as 10.2."
