people have been hard on rabbit r1, but ultimately it is a step toward future I feel. And they bury further down in the article that it requires permissions that the android won't grant.
It's fine to take baby steps, but you can't sell a proof of concept as a real product. People will hate you, and it'll taint their perception of similar products going forward.
That’s just because it needs installed as a system app (read: shipped with the ROM) to access system level permissions. Android will grant them, since it grants them on the Rabbit’s ROM like android would to any system app.
