If Apple let me spec a physical ESC key, inverted-T arrow keys, and native 1920x1200 point screen size @2x on the existing form factor I'd be VERY happy. Assuming, of course, the keyboard is actually reliable.
As for the ESC key, I rebound my Caps Lock key to Esc & Ctrl. Works great!
It would be a huge migration for me. Everything I own is tied to one of a few Gmail accounts. My photo history, my uni work in GDrive, my contact lists, my email history, everything about my entire online identity. I'm just increasingly fed up with how Google approaches privacy.
The ifixit tear down shows that the 2019 model has done nothing to fix the issue. I highly recommend the Dell XPS over a macbook pro. The form factor is very similar but the hardware is much more reliable and fixing it is way way easier as most parts can be replaced separately.
I recently switched to iPhone after using Android devices for many years to get away from Google and that was actually a purchase I can recommend. The Macbook Pro, not so much.
