I gotta say, this is the first time I get excited about a machine in many years. If it does what I think it does, being able to handle 3D projects, rendering, etc... fast, it will be a game changer for sure.
One good think about apple laptops is that they last.. a long time!
They are extremely expensive, but if you manage to work with 3D, and get 2-3 nice projects, or 10 smaller budget projects, the laptop will pay itself.
And you get to have a nice machine for at least 5 years. My macbook is here with me, working nicely (well, speakers started to have some weird problems) since 2013.
I will wait and see though.
A friend of mine already does bit of modelling work in a very small macbook pro m1, and he says he is super happy with how fast the machine is, and this new m1 pro being 70% faster from what it was already a good speed. Impresses me. Specially the portability of it.
