You've said Windows 7 scales reasonably well, and I know from experience that Gnome does too. The real question is: why doesn't desktop OS X scale better? For the past three major releases of OS X I've been hoping for a move to resolution-independent "fixed-size" interfaces. That is, the interface will take up the same physical size on any screen (unless you choose to zoom it in or out). What's holding them back?
