I am looking to buy a new 20" iMac. I officially NEED the computer by July 10th but would like it now. I am wondering if i should wait till July to make my purchase or order it now. I am willing to wait if Snow comes out before then but I am unfamiliar with how Apple does all this releasing stuff. Also i am wondering if there will be any minor upgrades or price drops soon to the iMac. What would you all do? Thanks in advance.
