I just got the 21.5 inch iMac, replacing my 13 inch white late 2007 Macbook. I am thinking about exchanging for a Macbook Pro because the screen is so big! It looked cool in the store and I got a great feeling playing around with it, especially in the standing up position, now that I have it on my desk (and all the lights aren't shining on it lol), the screen is HUGE... I don't know if I'm just not used to it or not. Did it take you a while to adjust to it? Did it have a different feel on your desk than you thought? Do you think the screen is too big?
