Ok. So I got into a debate about Mac and Windoze. At some point, the debate came down to Aqua and Aero. What I wanted to know was why does Mac OS X Tiger only require 256mb of RAM has the ability to run Aqua as the default (and only) UI. Whereas Vista is requiring a whopping 1gb of RAM so that a user can have the Aero experience. Does this have anythiing to do with the Quartz layer of Mac OS X? In my understanding of Quartz, all of the "Core xxx" components are able to make calls to the proper hardware and make efficient use of exactly what it needs. Does this have anything to do with why Mac does not require more RAM? Also, I was told that Vista is able to take advantage of "Extreme" branded hardware, mainly the GPU, to accomplish something similar to what Mac OS X does. With that, why does Vista still require 1gb of RAM just to run the UI?
