> I think they missed an opportunity by not making the surface of the battery a trackpad. Apple for the most part doesn't merge two unrelated functions in a peripheral or component. For example, they never did the "2 in 1" thing with the Mac that Windows vendors did by having a tablet using a touch interface that was also a laptop using a keyboard and mouse. The result was a device that wasn't great at being either a laptop or a tablet. I have a Surface 2 in 1 and it's not a particularly good experience. The early adopters of the Apple Vision Pro will already have mice, trackpads, etc. on their Macs and iPads that will work just fine.
