Newson makes beautiful but slightly pointless, expensive stuff, the kind of stuff most designers love to make. Jony was reined in at Apple forced to constrain his designs with economics of mass production. Both Jony and Apple benefitted from the discipline. I expect the Jony Newson combo will be making over-designed tech like the Porsche LaCie hard drives. It's not that the design doesn't work aesthetically, it's just do you really need a fancy cover for a Samsung hard drive. With tech it's always what's inside that is most important.
On the other hand, Apple badly needs more well-designed peripherals. Software for bathroom scales, cameras etc is usually rubbish. We're at the stage now where there should be an App Store for physical stuff, like monitors, trackers, measuring devices, toys, vehicles, drones, chargers, containers and covers (other than Amazon). Maybe Jony can do something about this.
