As does the precision line. I have a 5520 and it's absolutely rock solid.

I don't think Dell get enough credit for how compatible their systems are in the high end and what kind of build quality you get.

In my opinion Dell stuff is the only thing on the market that could take over Thinkpads mantle as "Best laptops on the market".

I agree. This is my Thinkpad killer. HiDPI screen is gorgeous, keyboard and touchpad are fine, battery life is 10-11 hours in Arch, all of my media keys work, build quality is phenomenal. I haven't been able to get tear free video working, but I haven't ventured past xf86-intel-video yet on this machine.

Dell has really been impressing me. Their monitors are great and so are their laptops.

Try to use vaapi decoders. mpv has some flags for this and you need some packages but thats how I got tear free video (and lower resource usage on video too)

I started with an XPS 13 Developer edition. It had some minor issues, but I generally agree it was a good Linux experience.
