Bought my wife a new 13 inch mac pro book and know it is my turn. This week I am going to buy a 27 inch Imac. It it worth upgrading from the I5 to the I7, ITb or 2Tb. I will be having 8Gb RAM? Does anyone think they will come out with a new model anytime soon, what about antiglare screen on new models? Sorry for all the questions. My wife and I have left our PC's for Mac. I have been loving her laptop.
