As for optimal typing layout.
Its useless if you are used to QWERTY, very hard to learn different. Like 99,9% keybs is QWERTY layout. Beside that I dont think I could re-learn and keep my average of 70 WPM. :/
Keyboard is interesting, but 4kHz .. hm, aint PS/2 actually faster? It was definitely faster and more responsive compared to 1kHz. Still miss it.
Keycaps, I change that basically on every keyb I can/need. So, pretty much all of them as long as its possible. For me, best keyb doesnt even have keycaps.
Unsure if stabilizers can be fixed there tho. And limited SW is quite bad, on other hand I dont want much from my keyboard, apart typing and if needed to, re-assign keys (can be done via other stuff anyway). So SW is probably fine for most as long as it works.
TOF is.. ehm. Feels a bit like "I have 4 cameras on my cellphone, one is great, others are there". Thus that cellphone is obviously better than one with one great camera. Even while those 3 are basically useless. Im sure there are ppl that appreciate "more of stuff". Just me aint one of them.
Nice review, thanks for that.
