It is always easy with new tech to claim "this new whatever is stupid, the old way works better," because initially it always does. But tech keeps evolving. What is stupid is denigrating new tech at its very inception just because it is (always) initially a soft target.The only effective way of typing is via physical keyboard. Humans have this really great feature, thats called "fingers", which allow them to touch, feel and use stuff, even when not looking directly at it. Believe it or not, It's highly effective. But unfortunately, majority of developers and UX designers these days think, that the answer to "what comes next after physical keyboard/buttons?" is a solution via touchscreen. You can see this sheer stupidity in modern cars like Tesla, Mercedes, Audi, BMW etc. where they keep removing phyiscal buttons, and replacing them with touchscreen. Typing "in-air" like this keyboard utilizes, is on same level as touchscreen typing - It's annoying, it's cumbersome and it's stupid.
That said, data input has always been my question about how well AVP will function. How it evolves will be interesting. Personally I would like it if we could get more lap-friendly, voice-friendly BT keyboards with numerical input pads. [Anyone with suggestions, please respond.]
