$2 Dollars! Can u send me the name of your supplier (off-line of course)- for every ultrasonic pen you can get at $2, I'll happily pay you $30+ and my right arm.. jokes asides (seriously the tech behind making the ultrasonic stuff work is heavily patented and expensive).

BTW the inking weight system has nothing to do with the inking state of the pen (which incidentally is Binary), (so the fact you couldn't tell i guess is a complement to Sumo) the transmission of which is IR not ultrasonic. Last thing, there is indeed plenty of latitude to address several aspects of laginess in iOS that arn't restricted, you just have to look for them, and be prepared to invest a lot of time. We know because we're doing it right now, and your right - it is early days, and thanks for the thumbs up - we are indeed coming up with something:)
