It would be a normal typewriter for $400 (but no more) if at least there was a full-fledged numpad, but it is not here. and the tactile quality of fast blind typing is disgusting in reality. This is a useless device for office work and work in Excel. I can't even imagine who needs such a "miracle". Unless very pretentious people.
And I don't believe in native contrast of 1800:1 on semi-matte IPS, it's impossible a priori. The tester did not check the gamma curve, I am 100% sure that dark shades are simply not visible there for the sake of artificial contrast, which is most often the case when manufacturers try to create the impression of a contrast screen on a cheap panel for a penny.
The noise is too high under load, and it will be there almost all the time under 50% and above even in surfing. It's no good, except for a noisy office.
I would also understand this strange device as a surf machine (where the keyboard is minimally necessary), but it has a completely lousy screen in terms of color reproduction (despite the fact that at this price it MUST be set to 72% NTSC) and there is not even an EDID autocalibrator (which visually slightly improves the perception on cheap panels), which is only available in SoC from AMD.
As a result, the saying - the miser pays twice, is fully justified.
