At a first approximation, everything in the actual machine works. The touchscreen was picked up immediately, the machine stays pretty cool, it's reading about 7h40m in battery life (this is the 4K model with the i7 and 16GB of RAM; I expect more like 4h to 5h). I really like the keyboard, and the keyboard correctly turns off when it's folded back.
This seems at least as good as the XPS 13. Only downside so far is that the pen is a little finicky in Krita, but I haven't tested yet if that's a battery problem (it popped a battery warning right away) or a software problem. But this thing feels really good. I'll probably keep it.
Thanks
