I guess that I am not completely satisfied so far. Most because of noise, battery life and heat. But also pure performance. I am new to Blender but so far I really enjoy it! Therefor I wonder this:
My question is (I can still return my new computer and change it for another one) if you guys have a favourite laptop or even desktop that works really good with Blender?
You shouldn’t have any performance issues with that hardware (At least hardware related, and not because of Blender’s own issues). Can you elaborate on where you saw performance issues with Blender? Can you give examples of .blend files or doing what kind of work in Blender?
If you don’t need portability, a desktop PC is always recommended.
If those are you main issues, perhaps you should look into Apple laptops since they’re effectively noiseless, battery lasts a long time, and stay cool.
