OS X (and by extension iOS) uses a form of Display Postscript with some PDF-style improvements they dub "Display PDF". There has been a lot of work towards resolution independence in the core OS over the last 3-4 years to allow the UI to scale to meet the dimensions of the screen, rather than the pixel size.
In the case of the iPhone, it also helps that they simply doubled the pixel count in both dimensions, makes it easier in the short term.
The problem with using Display Postscript for monitors is that monitors are still pixel based. Why not offload the work of figuring out the pixels to the GPU/CPU/OS which is already doing that work? It's completely possible to move away from pixels/etc without having to introduce a new type of monitor (and the tech that drives displays isn't moving away from using pixels anytime soon).

It's about the DPI/PPI.
iPhone 3GS - ~160PPI
iPhone 4 - ~320PPI
iPad - ~130PPI
Right now, the iPad has the least dense screen, which matters for things like text. The PPI for the iPad is lower than most eBook readers, and it does show.

It's 'cause when Bill Gates was asked if he'd develop for NeXTstep his answer was, ``Develop for it? I'll piss on it.''

Will, nice to see someone try to give a history lesson, but this is woefully off the mark. OS X does have a variation of Display Postscript (see above), it's how the Quartz engine runs.
And the real history lesson is that Cocoa was the Yellow Box. Blue Box was the proposed emulation layer. When OS X became official (post-Rhapsody), Yellow Box became Cocoa, Carbon was added, and Blue Box became Classic.
