Be careful about the quality control on the HP Envy X360. The specs are great on paper, but I had several issues:
Terrible display panels. They actually use at least 4 different panels on this models. All of them are rather dim, which doesn’t bother me too much. Units with LG and AUO panels seem ok. The ChiMei panel is utter trash with abysmal colors and dimmer than the others. Some units have really bad backlight bleeding.
There are a bunch of more minor issues, like the webcam looking purple in daylight. Apparently it’s tuned for fluorescent light, resulting in strange colors in natural or incandescent light. That’s a broader longstanding issue on several HPs, not just this X360 model.
The build quality is just medium. Opening up the laptop is a bit scary as it requires some force to pry off the cover, and the edges are RAZOR sharp. No joke, be really careful. I had to wipe blood off components…
Other issues: I was a bit disappointed by the (lack of) alignment of some of the trim. On my first unit, SD cards would get stuck in the card reader. The weight (~4 lbs) and size (15") are a bit much for a device marketed as a tablet. Battery life seems ok at around 5-7 hours, but I never ran it down completely. I kept getting the feeling that things, eg the fan, might break down eventually. I tend to keep my computers a long time so I want great quality. Touch screen + pen are nice bonuses; they’re ok but not great, say compared to lenovo. About a month ago, the touchscreen wasn’t working in Ubuntu 18.04 beta (kernel 4.15 I think).
The Ryzen 7 2500U is nice though. Upgradeable RAM to 32GB. 2.5" bay + NVMe slot. The 2.5" bay needs a special connector (SATA to ZIF ribbon cable), so if you got a unit without the HDD you might need to order it separately.
Yes, I’m a nitpicker. I ended up returning it. I’ll wait for a more refined model. But those who are less picky might still really like it.
