Hey first time poster here. Love LTT videos and this one was great. I just lost my MBP 13'' and need to replace it. Reading this, it sounds like the new 15'' is a winner. Would anyone suggest what the best bang for the buck is and what parts are worth upgrading? My work is primarily devy, in the application security space. So application development, VMs to setup environments as tests and pen testing tools. I do like gaming on the side so wonder if the GPU upgrade is worth it as well.
