I saw the 2015 12" Retina M-5Y51 1.2GHz 8GB 512GB model selling for $1099 brand new online. Do you guys think this is a good value? Is the performance bump on the 2016 model worth spending the extra money or is the 2015 model alright. I wouldn't be doing any gaming on this machine as I have desktop for that. This would mainly be used for web browsing, emails, and light creative work.
