I own a 2009 27" iMac that luckily just had its hard drive so kindly replaced by Apple out of warranty. I'm choosing to sell this iMac because this is now the fourth drive being replaced. It's in great condition and it still has all the original packaging. I'm hoping to get around $800 for it. Once it sells, I'm going to being needing a new Mac. This where all of you come into play. I'm not sure which direction to go. I really never considered the rMBP before, but it's such a beautiful laptop and I love that it's mobile. The biggest draw back for me is that I'll be getting a less powerful machine, smaller screen and something that can't really be used to game on. With the iMac, it's ideal for video editing and gaming, which are extremely important for me. The biggest drawback is obviously that it isn't mobile. I'm leaning towards the iMac now, but who knows?
