Hm. Yes, you're right. But from the beginning. The UI has a certain resolution "in mind". Sure, you _can_ use a 17" at 1280*1024, but IIRC, that's a higher resolution than originally (by those who made the Mac's UI) anticipated. But whether you're using a screen with 72 or 96 or 112 ppi doesn't make much difference. We're talking about much higher resolutions.

And to elander: Yes, if you're using a 72 dpi graphic on a 300 ppi screen and it's scaled nicely, it won't look much worse than a 72 dpi graphic on a 72 ppi screen. But it won't look as good as a 300 dpi graphic, not as good as a vector graphic etc. If you take the current Mac OS X UI and scale it, it _does_ look bad. If it's good enough for you, that may be so - but it's not what we envision with high resolution displays...
