Rhapsody to OS X in 2 years
I was just thinking back to when Mac OS X Server 1.0 came out... the one based on Rhapsody, with the YellowBox and BlueBox and OpenStep-like Workspace Manager (Finder) etc.
I was at the Apple campus the day it came out doing WebObjects training. To think that 2 years +/- a few days later, Mac OS X 10.0 came out is just astounding. The two are completely different beasts. And now we're a little over 2.5 years later and we've had 3 major OS revisions.
Very impressive. Kudos!
