John Siracusa marking Mac OS X’s fifth birthday (10.0 shipped five years ago today):
A side-by-side test-drive of Mac OS X 10.0 and 10.4 is shocking. The eternal debate is whether this gap exists because 10.4 is so good, or because 10.0 was so, so bad. That said, Apple’s ability to plan and execute its OS strategy is not open for debate. In five short years, Apple has essentially created an entirely new platform. Oh, I know, it’s really just the foundation of NeXT combined with the wreckage of classic Mac OS, but I think that makes it even more impressive. Two failing, marginalized platforms have combined to become the platform for the alpha geeks in the new century.
