Your content is excellent imho. I like the clear presentation and 'to the point information' delivery.
I have an old magic keyboard and I really like it. It was noticeable that the sound was slightly better typing on the magic keyboard and depending on sensitivity of the person that could be more important or negligible but worth noting. I'd also suggest providing information on weight in grams as pairing these slim keyboards with portable devices such as pairing with a tablet then using RDS/VNC to run the device as a thin-client using these excellent keyboards (with mouse) is an important specification to consider to keep weight down as much as possible for portability. Naturally that's just a suggestion but total weight adds up:
* tablet, cover, keyboard, mouse, +dock?, travel sleeve
The magic keyboard = 239g
Logitech Pebble Keys 2 K380S = 415g (+ batteries)
Another keyboard designed for Apple devices only but have the 3 devices pairing feature is:
Satechi Slim X1 = 290g
Overall, given the high price of Apple's keyboard it really should come with that device pairing feature and as you say change to USB-C but otherwise you can see a lot of merit in the actual keyboard and it does look nice as tends to be the case with Apple design but they do charge you for it!
