Every windows computer/android phone I’ve ever used has crashed at least once a week if not daily because they’re trying to account for all hardware configurations possible my MacBook and iPhone have crashed maybe 4 times combined in their lifetimes. Having my app im using on my phone preloaded on my iPad and mac ready to go when I pick it up, my mac automatically sensing that I put my iPad next to it and automatically connecting the keyboard and trackpad to it. Being able to run iPhone apps on my mac without emulation. Projecting my iPad or iPhone display to my MacBook. I’m sure theres so much more im missing.
