i have the 2019 mbp, bought reluctantly earlier this year after my 2015 went wonky. based on what i’d heard, i wasn’t expecting much, but it was clearly an improvement, even if it was incremental (touch id, bigger/brighter screen, better sound). the biggest obvious lack in the upgrade was the performance-battery life tradeoff, which is entirely on intel stagnating for over a decade. apple addressed these most glaring issues via the combo of m1 and more battery in the 2021. usb-c or touch bar were minor issues in comparison (that notch tho…).
