I'm now working with a Dell Precision 5530 which costs around 3k on its current specs.
The good:
- It had ubuntu 16.04 which means the hardware has good compatibility with linux and you don't need to pay for the windows license.
- 32Gb of ram, and it supports even more.
- The 512Gb NVMe SSD is very fast.
- The battery lasts several hours on non-CPU intensive tasks, I haven't need to charge it when using it for browsing the web on non-working days.
- Even that the screen is 15", it is actually smaller than my precision 3510.
- It doesn't get as hot as my 3510 gets sometimes.
- I'd say that the keyboard is decent.
- It has more input ports than the macbook pro.
- It's built from a decent material instead that my 3510 which is just plastic.
The bad:
- When I installed ubuntu 18.04, I found an issue with the nvidia driver which I was able to solve, if you want to get ubuntu preinstalled, the only choice was to get the nvidia P1000 included (even that it seems to have poor support), if buying again, I'd probably get Windows preinstalled instead to avoid paying for the graphic card.
- The AC adapter is lighter than the one from my 3510 (which gets easily damaged on the port, I expect this to last longer but we'll see).
- The trackpad is not as good as it could be, it is common to paste content accidentally (I believe it detects the middle-click gesture), I guess there may be a software trick to avoid it but haven't invested enough time, I can live with the issue.
- As the screen has tiny borders, the camera is placed below the screen which is something I laugh about each time I do a videocall.
Those are the details I can think about, I'm far happier with linux on dell laptops than what I ever was using a macbook pro.
