Yet another device that's always on and always listening??? No thanks. No such devices are allowed in my house (the closest such device I have, my phone, has voice control shut OFF).
Rechargable battery? Yep, that would be good. But if I want to find the remote, I'd rather have a paging button on the Roku device itself. And while they're at it, the quick-access buttons should be programmable, not hard-coded to services that end up going out of business anyway.
Not another device with an integrated battery destined to become yet more junk once the battery no longer functions. Why not stick to tried and true AAA batteries? Rechargeables are ubiquitous and you don't have to throw away the entire device when a battery wears out. A much more sustainable option.
