Finally, models would need to continually adjust for changes in competing mortality risks, which also change over time.
You'll likely see other stylus makers move to take advantage of the same changes with competing devices, but FiftyThree will be the first to offer it, and it could change the way digital artists use their iPads, combined with the existing palm rejection and blending features the company already offers on their drawing software and stylus combo.
