Remember all those feature phones with a plethora of custom operating systems? Almost none of the users cared (or knew) what the OS was. This is an OS for that kind of device. Nokia is shipping it right now.
The target market might not care or know what the OS is, but they'll want to use software they're used to: Google Maps, Facebook, Facebook Messenger, Snapchat, Tinder, Skype, games, etc.
I'm just saying that whatever OS will be useless to a lot of people if it doesn't run what they want it to. One way to do that is to make it compatible with Android apps, which have already a version of virtually every major app.
Are you sure you know the target market you're speaking of? They're not coming from Android world, so they're probably used to exactly the kind of services these phones support.
