Wow! Slow down speed racer.
You cannot just hope straight from a sandbox to a real world does-anything-for-anyone OS. Aqua is working through the gap between toys and real tools - something linux is good for since it runs on a real computer, but is still a sandbox OS. Think of it as going from your tricycle to a bicycle with side wheels.
If you jump to soon you might not be able to cope with all the freedom and power and end up diving of a cliff into the great blue [-]see[/-] screen of death or you could go about clicking and fondling all sorts of binaries out there like a teenager in puberty and end up with a virus.
As they say - with great power comes great responsibility.
