I am also still on the 2012 non-Retina MacBook Pro and I love it. I have added an SDD, moved HDD to DVD slot, replaced the battery and added an extra 8gb of RAM (will upgrade to 16gb when I can justify it). I love my MacBook Pro and am dreading when I have to upgrade, the price of buying a new one doesn't seem worth it considering just a moderate spec upgrade.
