I agree with so much of what you said. I too had great hopes for the keyboard/dock and ordered it with my Chuwi. Again, as you said, I would have been much happier if it had a battery, or the option at least, instead of weight. In fairness, the battery is pretty decent IMHO, but I keep brightness cranked down to 15-20% most of the time. My suggestion re: opening keyboard was predicated on mine having a bunch of screws holding it together, didn't realize that had changed, but I bet you could find a video or simply use a spudger and do little or no harm if you're gentle and it is in fact designed to be opened again.|
My biggest complaint was the report that the being attached to the keyboard when shutting down was causing the tablet not to power down fully and causing battery drain and other start up problems. Happened two or three times to me, and once was more than enough for me to seek another keyboard solution.
I so very much wish they had brought a thin keyboard/cover to market designed to work with a case with a folding support, or just had one on the tablet's rear to begin with, to hold the tablet up ala Surface... I don't use the keyboard an awful lot during the day, so an OK portable solution that preserved the lightweight tablet idea would have been fine for me, perhaps with a better keyboard(bluetooth, etc.) to use when needed for long sessions.
The folio cover they produced could have come with an adjustable hinged support on the rear and a thin bluetooth keyboard instead of the plastic front cover and would probably have hit a sweet spot for many. I'd have paid $40-60 for that, rather than a heavy clunky keyboard for which some complain of issues keeping connected. Of course, that folio suffers from the plastic being a mite brittle and generating cracks near the tabs if you remove it even a few times. I've gone through two in 8 months or so.
