Hi, Sorry to bother you guys! Been waiting to upgrade my 2013 rMBP and finally have these new ones to choose from! My questions are: 1. Do the 15" 2016 MBPs have removable SSDs? Should I upgrade to 512gb or save my money and buy a third party SSD?! 2. I know nothing about GPUs. Is there any point of upgrading the base option if I'm not a video editor/all I do with video is watch it? Thanks!!
