Hi, I was just reading arstechnica's article about OSX being 5 years old (today!). They linked to an article they did on the developer preview of OSX 10.0. It is really interesting reading, and very suprising to see how well the system turned out since those gloomy days. What was really surprising to see is this: Looks just like today's "build for both platforms" option, and this is BEFORE 10.0 was even released. Plus, they explain how Apple is developing the system cross-platform, while it sounded in Steve's keynote back in the day that is was a very big "secret".
