I should have been more clear. If leopard doesn't support some higher dpi screens I'm not going to be a happy camper.

Saying that "people can only comfortably see things at 72dpi, so that's as high a dpi as we sell" is complete BS, and based solely on the fact that everything being displayed was created for a 72dpi screen. One of the things apple has done well is told people what they needed even if they didn't want it - e.g. firewire and USB.
