I am a fan of the non retina MBP, in fact I purchased one about two months ago now. I did a lot of research until I finally decided to go this route but I am very happy I did. I wanted some expandability as I am a bit of a control freak at times and like Options...
I purchased a pristine example of a Mid 2012 MBP non retina for $700. It was the 2.5ghz I5 13"
It came with the standard 5400rpm 500gb HD and 4gb of ram.
Immediately after purchasing I upgraded the ram to 8gb(eventually will go full 16gb). Shortly after I purchased an SSD and an HD Caddy to replace the Disc drive. So, I now have a 500gb hd for media purposes, 256gb SSD for bootable and apps and 8gb of ram.
I was coming from a 2007 MacBook so I am/was not used to the Retina display so that didn't bother me at all. Similarly, I looked heavily at the MacBook Airs (planned to max it out on purchase), but I wouldn't pull the trigger and the specs I wanted just weren't there. My main uses are media consumption such as youtube, web surfing, movies, etc. But I do a fair amount of audio production, some HD Video editing(I also have a full custom windows desktop so the power wasn't to much a problem, although I still wanted to be able to "Play") and Server Administration at work. Also, Having only the HD4000 graphics weren't as big of a problem, mainly because of half of the pixels it has to push; likewise, If needed the power, Thunderbolt h.264 encoders are coming down in price if I need to do some hard core video editing and not have to rely on the GPU.
