cheers 709!
And to further make this thread about RI and not HD Powerbooks....
Thinking about MS's crap-ass font and image enlarging solution (as opposed to a real RI GUI) reveals another issue for RI GUIs. The remaining problem even with a nicely implemented vector-based RI OS X Tiger is still web graphics. Without scaling those 72dpi images (like Windows does yuck), page layouts are going to get funky. Images on web pages will be teeny on those uber-high pixel depth monitors and and the fonts would be all out of proportion comparatively.
Seems like the solution would be to allow web browsers to use higher dpi images and do scaling (down if you can help it). Afaik currently web browsers don't respect "size" settings (picas, inches, cm) on our 72 dpi web graphics, displaying them as simply pixel x pixel dimensions. In order for them to scale we'd need to start treating them like print graphics where you have a specific physical size and assign as much pixel depth as you need (or can get away with). Problem being that suddenly web pages would probably need to at least double in bytes because of this. So sorry 56k users. :/
