Mac OS X 10.1 debuts at Macworld Expo today. From MacNN:
* Jobs launched Internet Explorer in OS X 10.1, and it took only one bounce to appear on the screen. He also showed the resizing and minimizing were enhanced dramatically in terms of performance.
OS X 10.1 sports DVD playback, CD burning in the finder, support for 200 new PostScript printers, and new networking functionality. There is also full support for managing AirPort base stations.
Jobs then debuted Mac OS X 10.1, saying Apple focused on faster window resizing, menus, and application launching as well as improving the Aqua interface.
