John Siracusa looks at his reviews of the OS X preview releases and the first 10.0 release.

What’s most amazing is how gracefully things seem to have improved in those ten years. The old screenshots now look dated and sometimes downright ridiculous, and Siracusa’s evaluations were nothing short of dire in the beginning, but it’s slowly and steadily become the clear market leader.

One of the best things about Apple is their willingness to put something out that might be a bit of a reach, and then to go back and iterate and fill in the gaps. They pay a boatload of attention to making it a great experience in the first place, but they are always willing to acknowledge that improvements can be both subtle and major.
