A counterpoint to those suggesting thinkpads, specifically the pxx range. I have a p50 thinkpad -- It's a wonderful laptop, but as a linux machine, it's not great, yet. For one, I have a M2000 graphics card, which sometimes doesn't play nice with external monitors. I also have a 4k screen, which linux is NOT optimized for. My GRUB menu is microscopic, and I just haven't gotten around to fixing it. Ubuntu seems to handle this all OK, but it is by no means flawless. I also generally have terrible battery life, even with TLP and a bunch of hackery to disable the 2nd GPU.
