Hi, I've been following the discussions on the possible iMac refresh and am considering my options. My PC is on its last legs and I'd like to get my first Mac, primarily to use Aperture to sort my photo library (nothing major, just shots of the family and holidays), as well as basic movie editing in iMovie. I'd also want to use Parallels to run a few programmes like Microsoft Money until I've found Mac alternatives I like. Nothing too taxing. Size wise, I can only fit a 21.5in iMac on my desk - I'd be sitting too lose to a 27in version I think. I've been looking and I can get a refurbished 21.5in 2011 iMac with a Sandy Bridge i7 processor for around the same price as a brand new model with an i5 processor. If the new iMacs don't appear this week, I'm not sure whether I should wait or just go ahead and purchase a Mac now. Other than an upgraded Ivy Bridge processor and USB 3, what else might the new models have that would be of benefit to me? Would I be better off getting an i7 Sandy Bridge processor on a refurbished iMac, rather than the 'standard option' Ivy Bridge processor on a 2012 iMac? Thanks in advance for any advice you can give me!
