If you understand what graphene is for and you need that then you wont wait.

Even if you don’t understand what graphene is for or if you need it and are trying to make a decision: graphene on new and used pixel phones works as expected now. It has been tested and proven against many different intelligence and surveillance apparatus. Motorolas new phone may not come out at all (it’s more likely than you might think!), may not end up supporting graphene (or graphene may not end up supporting it!) or it may have serious flaws that need to be addressed (it is a new hardware platform after all!).

If you need it now don’t wait.
