My 2011 MBP was just getting too slow even with the 16GB RAM upgrade and SSD, so made the jump to 2017 MBP. So far no issues, hopefully it stays that way. Enormous touchpad was annoying at first, got used to it, the scissor keys was very weird at first, got used to it, the touchbar I hardly use, feels strange hitting a virtual escape key when editing in vim-mode in intellij
