I have purchased two Lenovo T580 laptops within the last year, and both worked flawlessly with Fedora with zero tweaking. Both machines are running great so far. An older Lenovo I've had for a few years did have a hard drive die, but Lenovos are so easy to service that it was cake to replace the drive. If anyone from Lenovo is reading this, thank you for making it so easy to service the laptop for a user.

I have had a few Dells and I think hardware-wise it is the best, but that dual video card setup never worked quite right. Also until Fedora 29 came out (with a newer kernel) the only distro that I could install was the stock Ubuntu that came with the laptop (which didn't have full disk encryption, unfortunately).

I would recommend a Lenovo T580 or Dell XPS 15/5520. I think the Dell hardware is actually nicer than Apple, which is a high compliment.
