I have a mid-2012 MBP 13" non-retina. When I bought it, I just got the base model. I am about to have a $200 credit at BH, so I have a couple options:
1 - Upgrade to 120g SSD and 8gb ram
2 - upgrade to 16gb ram
3 - Upgrade to 120gb SSD and then save for a short bit and upgrade to 16gb ram
I have a 21.5 iMac but since I got the MBP I have pretty much solely used it for editing, but that is also because I don't have the iMac set-up in a good workstation at the moment.
I use photoshop, illustrator and iMovie mostly right now (what would Lightroom do for me, I have never used it).
