Is it the same as the app 'Update center' already installed by default on the Z1?
I don't like it to be forced to use a operating system on my computer (not windows not OS-X but BSD). Also i prevent to use the bus connectors(like usb) a lot on the Z1. So that the bus covers stay waterproof. (i use wifi for transfers between Z1 & computer)
