You made a great choice!After days of hesitation, I finally decided to go for the 16-inch model.
Before that, my notebook only featured 13,3" so when I tried the 16" for the very first time, it was indeed a bit of a shock. Before ordering it, I was afraid that it would be way too big and heavy but not at all!
The 16-inch model is heavy for sure, you'll feel it in your hands but you can still perfectly bring it with you in your backpack if necessary. It is not too big, nor too small and its weight is appropriate (after all, this wasn't a problem at all 10 years ago).
As it's been pointed out by many users, the mini-LED Liquid Retina XDR display is gorgeous, arguably the best I've ever seen. Here also, there is a big gap between the MacBook Pro 2021 and the others notebooks. While the 14-inch and 16-inch are very similar, the 16-inch model is slightly more powerful, has better speakers, a bigger display (much more comfortable if you wish to watch a series on Netflix) and a better battery life. Honestly, I could hardly go back to a 13" or even a 14" display. The keyboard is excellent and the camera has been upgraded to 1080p in full HD (which should be the basis in 2022). Last but not least: the connectivity (MagSafe, SD, HDMI...) is back. No more adapters! The apps launch almost instantly (and I'm only using the "basic" model with the M1 Pro, without any upgrade).
If you're reading this thread and still hesitate whether you should order a MacBook Pro 2021 or wait for the next "generation", just don't wait - you won't regret it. I'm using Apple devices for ten years, and the MacBook Pro 2021 is by far the best notebook Apple has ever made.
If however the 15” M2/M2Pro Macbook Air features support for multiple external display and a wider range of scaled resolutions on certain monitors, I will gladly return my 16” M1 Pro for that!
