I'd rather have an OS that is nimble and responsive, that loads quickly and doesn't waste time and resources loading libraries that seldom if ever get used. Libraries should be loaded when a funtion within them is required by the system or is called by a user application. Same with preference files and other application resources. Just because the RAM exists to load everything including the kitchen sink doesn't mean we should necessarily do it. How much extra waiting could there be anyway with processors now in the 3-4GHZ+ range? I know the car analogy is kind of a cliche, but consider race cars. F1 cars have oodles of raw horse power AND are extremely lightweight! You don't see F1 teams respond to every gain in power with an urge to add more weight. If they did the way computer companies add "features" you'd have Formula 1 cars that drove like Winnebagos.
F1 cars doesn't have 5 seats, power windows, power sun roof, aircon for 5 people, sat-nav, 6-8 speaker MP3/CD/FM radio, in-car-TFT DVD players, electronic assist brakes/traction control, sound dampening insulation and 'etc'.
I rather have a ~1.5Ton Lexus than a F1 car.
