Hey fellow iMac-ists, let me ask a possibly very stupid question. When peeking at current-gen iMacs in stores, I couldn't help but notice that to my eyes the stuff on the 27-inch screen is smaller than on the 21.5-inch, such as the menu bar being not as tall. Is it just an impression due to the bigger screen and higher resolution, so that the menu bar looks comparatively smaller, or is it actually smaller? If so, how long did it take you to get used to it? TY!
