My points for the RM2 are:
- Simple design (both hardware and software)
- More affordable price (from the official page)
- Great integrations with mobile/desktop apps and chrome extension
- 100-day return policy
- Writing feel and joy of using the device every time I pick it up (realised this after purchasing the device)
Conclusion
After using it for a while, I realised I needed nothing more and nothing else than what it offered. So, even though other devices offer a more complete experience and wider range of features, I don't feel like I need them in my workflow.
This. It is an expensive but fantastic stylus.
