They probably think nothing
One more reason to use the fingers and just glue the stylus into its compartment.
(Sorry, I'm not being serious here
)
Why not use one of the Nintendo/palm/whatever styli and really glue the original into its compartment as not to disturb the overall device appearance? I'm using my fingers, no need for annotations and I more than once wondered if the stylus could easily be lost when I tote around my reader. I probably at least try some adhesive tape to get a more firm fit.
