Just get a MacBook Pro.

I don’t get the stubbornness that makes you choose an inferior tool. It’s a piece of equipment you need to do your job, just get the best equipment you can. Why would you sabotage yourself by using shitty tools?

If you’re a professional developer you really only need one main piece of equipment to do your job and it’s not even a lot of money to begin with. Compare this to many other trades. For example: a nephew of mine installs A/V equipment, basically a glorified electrician. He drives a €25k van with about €15k worth of tools and supplies in the back. I bet his hourly rate is less than yours.

Drop €4-5k on a nice loaded MacBook Pro. That’s, what ? One week of billable hours?

Do not get a Thinkpad if you're using it for graphic design. The screen color calibration is terrible (even when compared to low end devices)

Last I checked I think some of the Dell laptops have a decent screen (XPS, latitude lines). But they tend to be more on the pricer side.

I use a framework for my laptop. I brought my own ram and storage.

I got a Dell xps 9310 last year and I love it, it's small and powerful, everything I need for Adobe suite and DaVinci resolve.
