Intel Minis support that too, either directly or via SwitchResX.
SwitchResX even allows to flip the display on Intel Minis (right<->left, or top<->bottom) (useless, but fun), maybe on MacBooks too ?

Flipping displays has uses for kiosk developers and similar in-place display systems, where you might use a mirror or a reflection as part of the display system.

Plus, if you're just an ueber-geek who wants to, um, maximally actualize your digital personhood, you can set up a display behind you, flipped left<->right, and use a rear-view mirror, fixed to the monitor you're facing, to let you view the one behind your head!

Hmmm, gaming might find uses for that....

Anyway, speaking of rear-view mirrors, you can get those at auto parts shops, in a variety of sizes and attachment styles. Hmm, I feel a hint submission coming on....

What clown decided that the iPod calendar view didn't need to show you the Location field? I guess they always use the same room at Apple.
