nagromme said:4. Resolution-independent GUI! A TRUE, fully-scalable, resolution-independent interface, with everything scalable as a whole by a single global slider. See everything (menu text, apps, toolbar buttons, everything) larger OR smaller than we see them now. Show more detail or fit more windows? It will be YOUR choice, and you can change your setting at will. That means everything from window borders to stoplight widgets must be redrawn by apple at much larger bitmap sizes (and some vector images).
This is what I'm hoping for as well. It doesn't have to be 100% vector (such as icons), and it doesn't have to be a "live" slider either - meaning that UI elements could be pre-rendered from vector data into bitmaps, which would be used for display.
I think resolution independance is also an important step, simply because OS X is lagging behind here: Linux and Windows have had resolution independant UI's for years now. It's never good to have to admit: "Well, that's where windows is better."
