bobgillen and gmadden - thanks for noting emulator apps, they’re a useful point of reference.
Emulator apps work fine if you want a touchpad, and you don’t need your phone or its screen while you’re writing.
Most TextBlade users still use the phone during a typing session, either for other tasks, or as the primary workstation itself.
The phone touchpad emulator also doesn’t let your hand stay close to home row, so it won’t interleave easily with typing.
Just like legacy mouse or touchpad hardware, an emulator app still requires your hand to leave the keys, and reach over to a separate large object at the side, then return back for typing.
So all the same RSI issues still occur with an emulator app.
Can do quite a bit better here with a new architecture.
