Is this a good price for the 2015 refurb? I'm running a mid 2007 iMac right now which is going strong, but wondering if it might be smart to upgrade at this price since this computer's demise is inevitable.
Also, any comments on screen size? Specifically I have a 24" model, wondering if going down to 21.5" will be a noticeable downgrade. I do do some graphic work on this machine and screen real estate is always nice for that. Thanks
