I have a 2011 27 inch iMac that I love. It's amazing, but it's already starting to get slow. I have all of the money invested to get a new 27 inch iMac, one with a 512GB SSD and 16GB of RAM. I do know that WWDC 2014 is coming June 2, but I have not heard much about hardware. Last year was a dud when it came to hardware with just a new MacBook Air. Is there any reason to think that the iMac will be updated at WWDC 2014? Could it even be the long-rumored retina iMac? I would be willing to wait for a few months, but if a refresh is not expected until fall, then I will buy now then sell when the new one comes out.
