It's not marketing. I have both. I've used both extensively.Wahoo, the power of marketing hits strong on some 😮
As I mentioned just above, my 16" MBP is sitting unused. That's not marketing, that's real world experience. Experience that, despite only being able to run a single 5K external monitor, rather than the 5K + 4K I prefer to run, and despite not having the RAM I need to run some large VMs I like to run, I do all my work on the M1 MBP, and it's not even a distant consideration for me to go back to the 16" Intel.
