GigaOM: People often talk about the timeless design of Porsche’s cars: on paper they might not have deviated too much from the original idea, but in reality they have added more oomph, more features, and newer technologies into the car. I suppose one could say the same about Apple’s OS X operating system. I first started using OS X on the first Titanium machine released in September 2000. Sometimes the subsequent upgrades would leave my laptops wheezing, and other times they would make them zesty. But for nearly a decade, Apple has made OS X better and better.
