I have a 27" iMac that I love, but it's ancient. Photoshop and Microsoft Office keep telling me they can't update on it, which is fine with me. I would get a new one, but I don't think they make them anymore. I'm fine with limping along on this one. Best Buy has refurbished 27s for under a grand, but they still have the old processor in them (as far as I know).
