#1-3 make it much less attractive than Shima, but I'm intrigued by #4-7.
I know there's been some talk of integrating Alexa with Shima, and a case that can charge glasses seems like an awesome product that anyone could produce...
The ring joystick looks way too bulky to wear all the time. I'd rather have a touch interface on my phone, it would be barely more conspicuous than putting on a giant ring and fidgeting with it.
