Maybe this is great if like, wall mounting your tablet is your primary use case for it, such as a home automation controller. But I can't see the average user wanting to affix a wall mount to the back of their iPad.
As for consumers, I think it may be popular with those who like the minimalist approach, although you there are still cables, you are right. I think I'll get one though.
