I see no user's needs being a good subset of this machine's capabilities. It's just impractical. I have a 2012 rMBP and I'm thinking of upgrading to a refurb 2

I see no user's needs being a good subset of this machine's capabilities. It's just impractical. I have a 2012 rMBP and I'm thinking of upgrading to a refurb 2015 rMBP. I'd like to upgrade to the last good generation of MBP; it might be a while before Apple decides to start making good laptops again.
