Hey guys, I really need your help! Im really really torn between the 21.5" or 27". Im comming from a 13" macbook. I plan to keep this mac for 5+ years. The ram issue on the 21.5 concerns me as there is no future upgrades. I dont mind spending an extra 300 on somthing that will last me a while, i just want to be happy with the ammount of money im spending. Im worried the 27" will be to big for me. Im only a uni student and casual gamer. What does everyone think/ ordered themselves? Thanks so much guys!
