The Samsung Galaxy Note 9's S Pen gained interesting new Bluetooth capabilities over previous versions of the same stylus last year. Now, the OEM has obtained a patent to pack a whole camera into a version of the same component. This camera has a tiny lens, but also has optical zoom and a battery to power it.

The CMOS will be what...1/5"? And with an inevitably slow zoom...and with the transfer rate of BT we know there's no multiframe processing a la Gcam.
I would prefer them making the S-pen having a laser pointer capabilities rather than camera. What are you gonna do with that camera? Spy? A laser pointer should be more useful especially when do things like presentations.
They're great innovators and designers but they do certain things like this that are too abstract and not very useful.
