How are you finding it in linux? does everything work well?
[edit] my perception of the x360 was based on the older models, after reading this[1] on the stylus issues on the newer ones I am starting to wonder now

- Hi-DPI still deserves some love, especially if you're using different DPI on different screens (e.g an external 4k display), although ubuntu gnome seems to handle it better than plain ubuntu and definitely better than xubuntu.
- Tablet mode is funny: orientation sensors don't work well, keyboard & touchpad are not autodisabled in tablet mode, but then again it's not my use-case, so I just disabled all those features.
- (ok this one is a flaw of this particular laptop): When the display lid is closed, the touchpad is not auto-disabled, which results in weird mouse movement and clicks, since the lid presses on it. I had to hook an X-event with a script to disable the touchpad input device when the lid is closed.
Other than that - everything works flawlessly.
I installed Arch Linux for dual-booting, which was definitely hassle-free as you said. The convertible/tablet mode works great in Windows, but I haven't gotten it to work well on Linux (need to disable the keyboard & trackpad). But I can develop in Linux, then reboot and browse the web or watch a movie.
