Looks good, but first they need to fix the overheating issues and improve battery life.
I'd rather get a G3 stylus than a Note 4. G3 has great design, probably better build quality than Note 4, on screen buttons, laser autofocus, microSD also, IPS screen instead of AMOLED, etc.
Sounds more like a HTC One Max competitor, locked down to certain markets. If this was supposed to be comparable to the Note series, I'm sure we would have heard about this device much earlier. Like months.
