I’m holding off an MBP update for as long as possible until Apple: 1. Gets rid of the touchbar, 2. Fixes that daft keyboard, 3. Slaps Intel and makes them ship 32GB lpddr4, and an 8 core iWhateger.
We are also both heavily invested in iPhoto (which is why all our machines still run Mavericks).
A recent ThinkPad running Bionic has objectively been the best computing experience I have ever had.
