I'm considering buying the 21.5" iMac and am wondering whether to order it with 4 or 8GB of RAM. Someone once told me to get more than you'll ever think you will need that you can afford, when buying a computer. Right now 4 GB will be more than enough, but what about 4 years from now? I'm not a gamer, but who knows what will strike my fancy in a few years as time goes by. What's been your experience as iMac users? Did you get 4GB and are happy with it, or did you get 8GB and are glad you did? Thanks for any responses.
