Since I started this thread, I owe it an update. I was quite intrigued with the ASUS UX305CA when @Morgan_Hardwood mentioned it. It has an absolutely beautiful display. Ultimately, though, I couldn’t get past the 13.3" display size (largely due to UI text in RT and DT and code in editors)…I don’t normally glasses but would have to with that display size. ASUS also has a 15.6" UX501VW with a gorgeous display, unfortunately with a price to match.
I wound up getting a HP Envy 15-as010ca, which is 8GB/1TB and has a decent quality IPS FHD display, which I have not yet calibrated (too much time in that code lately!). It’s been problem free with Ubuntu 16.04 LTS. I’ve done a small amount of RAW editing in RT and DT, just to test, and performance has not been a problem.
