honestly yes, for me the additional 300g was a really noticeable difference going from one to the other which has definitely crossed a line for comfort, at least for me personally using the laptop on my lap the majority of the time.
2018 15 - slim and light (relatively speaking). Used this daily for 3 years.
2021 16 M1 Pro - thick and heavy - it’s already back in it’s box awaiting return!
I’m glad I tried it. It’s made me realise the 14” is the perfect device for me until apple release a 15 or 16 Air.
Thick and heavy? Naaa you just happen to buy the only 15" Retina MBP model in the last so many years that was slightly thinner and lighter. Yes if that is your preference the 14" is likely your favorite. But for the rest of us, not so different.
