I’m just imagining myself pulling out the stylus on the train/plane, dropping it, and watching it roll away forever.
The Palm Pilot experience. But that stylus was required for operation. Fortunately, just a plastic stick, so 3-pack replacement were cheap.
Millions of owners of Samsung devices somehow manage to not do that every day.
They thought of that! The cutaway of the stylus is a rounded rectangle, comfortable in the fingers but does not roll.
In any case, replacement stylii are very cheap online. Less than a screen protector.
