I wish Apple would re-think the form of a multi-device charging unit, and instead of being just a single plane flat pad, make one end an upright angled stand for the iPhone, with a flat horizontal area in front of the angled section to charge your Watch and AirPods case, since those would normally, expectantly, lay flat. This would make far more sense whether you've got it on a bedside table or at a desk, so that you can interact with the iPhone in a more natural manner.
This would also likely help with the thermal efficiency, by having the coils that charge the iPhone upright where they can radiate more heat energy into the surrounding environment.
I think the pad as it is now, looks more like something Apple would use in-store, kind of like a jeweler's display pad, not something I'd want to have on my bedside table or my desk.
