Correct me if I'm wrong, but don't you think that Apples long-suffering with perfecting products and/or features is a major contributing factor as to why Apple doesn't have "Vista-Like" problems?
Of course I would love to have all of the features I want now, but I would rather wait until the feature is perfected instead of it being incredibly frustrating do to a poorly thought out rapid release.
There are allot of smart people at Apple. It did not take two years to figure out cut and paste. Get real.
(Edit: Actually it is probably more than two years, you have to count the time for the development of the initial first gen OS)
