ryu1: Mostly agree. Except, HMD Fusion doesn't have wireless charging, it only has NFC. So, I would have to add wireless charging myself, and on top of that, try to make its hardware not interfere with NFC hardware.
Also, I got at Officeworks cheap pens that somehow are recognised by touchscreen. Messy - glitter ink left on screen. Not 100% effective. But, sharp tip capacitive touchscreen stylus!
