has anyone heard if there is going to be a new imac update anytime soon? i am about to buy one and was wondering if i should hold off.

i saw on one website (can't for the life of me find the link) that the last update was in september and not to buy one because there would be one soon.

also, when these "updates" happen, what types of things do they update? i know i sound absolutely clueless but i figured this would be the best place to ask.

if anyone knows anything, let me know asap!

if you don't need one right now, i'd wait til leopard ships on it at the very least.
