The battery in the Kobo Pen (and Adrawpen compatible) may last 6 months and can cost as little as 30c. So low a power consumption that the rechargeable versions of the MS Surface pen make no sense.
We won't know more till some realistic users here report on the Kindle Scribe.
Galaxy Note Pen

I'd not assume the Scribe pen works on a Galaxy Note. My three current Wacom stylus are incompatible: Bamboo USB tablet, Lenovo X200 screen and the eink reMarkable.
