My Mom has been happily using my 2007 iMac for some time now. I'm using a 2011 iMac. It is time for me to pass on my 2011 iMac to her and get me something new. Probably well past time. Do I try to sell the 2007 machine? Will it really fetch the $200 or so that seems to be the going rate on eBay? I'm left with the decision about getting the MacBook Pro 15" or waiting for refreshed iMacs in 1Q 2017 (I won't buy current outdated iMacs unless a machine failure forces me to buy). Alternatively, I could try to sell my 2011 iMac (works great with external SSD). I know some folks love that machine because it is last one with a DVD player. And mine has newish GPU and more RAM than she needs. I bet I could get $700 for it. Then I'd buy a new machine for her and me. Of course that would be a chunk of cash to drop in one go. And I hate doubling up on the same year's tech. I love that I got nearly ten years of use out of that iMac. Great machine! But all it runs is Lion and current programs don't run on it. And even though I back up her HD from time to time, I'm playing with fire having her use that old HD. And of course she would enjoy just having a better machine.
