Q: But Mac OS X already has a lot of these features. What's the big deal?
A: Apple has implemented some basic desktop composition features in Mac OS X "Panther," due this fall, and they appear to be quite impressive. But the basic problem with Mac OS X isn't going away: It's a classic desktop operating system that doesn't offer anything in the way of usability advancements over previous desktop operating systems. Today, Windows XP and its task-based interface are far superior to anything in Mac OS X. In the future, Longhorn will further distance Windows from OS X. From a graphical standpoint, there won't be any comparison. Expect to be pleasantly surprised--dare I say "blown away"--when the Longhorn UI is revealed in October.
