Subject: Re: 24" iMac
What is the advantage of a 27" iMac over a MacMini with a 27" monitor (my set up)?
I don't know what your monitor is but except for some quite expensive monitors their resolution is less than what you get in the "old" iMacs. 5120x2880 A 5K Retina display with high pixel density. One of those things once you use you hate to go without but it was a huge bargain considering you got a computer with it.
I plan to keep our iMacs as long as they are functional. Mine I upgraded to 40GB a while ago when I was doing a lot of virtual machines. At some point software issues will get us (i.e., things not running on older OS) and I will reluctantly move on.
