Here is my story. I have an 2011 15" mbp which I'm using for web development (part time job) mainly with Ruby on Rails and sometimes using visual studio with parallels. For fun I am working on some iOS projects and the usual stuff with simple photoshop editing - creating family movies with final cut etc. My wife needs a computer so long story short, my wife will take my mbp (with a new shiny 500 ssd) and I would get a new mbp. My ideal choice right now is to get the 2015 13" rMBP with 8gb/256 ssd as I have an external monitor and I can get it for 1600€ with 3 years finance plan (0% interest). My main concern is if it can handle parallels well without lag and choppiness. My next choice would be to get the new 13" mbp but it will cost me 2249€ (same configuration 8gb/256 with TB and same finance plan) or the 2015 rMBP 15" from eBay for 1900€. What do you think?
