Apple's OS update pace is very rapid. Almost one major update per year. At this blinding pace, Apple will almost have to include at least one great new feature with every release to encourage people to upgrade. Minor improvements and tweaks are always to be expected with these releases. So my question is: What great new feature will Apple roll out next? Jaguar brought Rendezvous. Panther brought Exposé. Each of these new features significantly changed the way we us our Macs. What will change our Macs in 10.4?
