Is there an application or something that would scale my mac osx to more than 1024x768 on my internal iBook G4 display(I run Leopard) even though my display hardware resolution would stay the same (1024x768)? I got the idea from watching a video on youtube where a guy is loading Widows XP on his iPhone through ParallelDesktop. I thought if iPhone has only about 300x400 pixels and it does run XP as a full display. The picture is just resized to a small display.
