This is a question... I know Leopard, OS X 10.5, is being released in the spring, but I was hoping to buy a new computer this christmas season... it seems that in the past Apple will let you upgrade OS for free if they release a new version within a certain time period from when you purchase a machine. For example, if I buy a macbook with 10.4, and then 10.5 is released 2 weeks later, can I get a free upgrade? Should I wait until 10.5 to buy?
