ok, earlier i was taking a screen shot (command, shift & 3) on my mbp and noticed it took about 3-4 seconds for the image to show up on my desktop. on my powerbook, probably about 1 second. Same with my sisters macbook. well, i also noticed that when the mbp is unplugged and just running off battery, it can take up to 15 seconds for the image to pop up on the desktop. what's going on? i'm running leopard, but i also have a backup with tiger and booted off of it and the results were the same. i took about 6 screen shots and they seemed to pop up slower and slower. on the 12" powerbook and macbook, i noticed it took just a little bit longer when unplugged, but still under 2 seconds. i think they are quicker because the screens are smaller. my question is if any owners of the 17" mbp could test this out on their computers to see if they get the same results. it's bugging the crap out of me! thanks.
