To me, it is quite revolutionary. I've seen many mobile keyboards/tablet keyboard covers that always seemed to have major compromises. I find it shocking that I can have something smaller than almost any of them, but be better for typing than the full-size keyboards I've had. I mean, if that isn't revolutionary, then why has it never happened before with mobile keyboards? And one keyboard that lets me use it on 6 devices and allows an almost fully customizable different layout on each? And if I want even more layouts, say for use on a specific game, I can create those too and install in maybe 30 seconds if 6 isn't enough!
I looked up the TAP. Have you gotten one yet? From what I've read so far, it was supposed to ship before the end of 2016 and, latest info I could find now says it will start this month, but I don't know if that has actually started yet.
It certainly is different, but to me that doesn't make it revolutionary in a useful way. From what I've read, I can see some special use cases, but not a substitute for regular typing.
They said it can register UP TO 10 gestures a second. That "up to" can mean a lot of things, including that it can't do so consistently. But assuming it can, that means it potentially can do 600/minute (120 wpm). Which would be really good for the vast majority of typists. But the more important question is how fast can people actually type on it. They wrote that they've seen 50 wpm. That's also pretty good, but since that is likely the best they've seen and who knows how long the test period was, it would really slow down many people. On the TB, we know just from Treg reports that it's gone over 100 wpm (I would love to hear what the fastest they've seen is). I've done over 90 and I'm no expert typist at all!
Also, if talking about the best speed, I know a person who types on glass at 80 wpm on a 9.7" iPad and 96 wpm on the biggest iPad without using auto correct tricks. So I'm not impressed with a best of 50 and I don't know if that is just characters or if some auto correction is involved on the TAP.
But for special situations, maybe TAP is good. I'll be looking for more info on it. I really want a list of the gestures to get all the other characters. Supposed to be 31 gestures (but it won't do things like control, etc).
