This doesn't even get into the dongle problem. The simplest example is that if you want to hook up Apple's flagship phone up to their flagship laptop for development, you need a dongle. And if you want to share one of their flagship wired headphones between the two devices, you need another dongle. Therefore if you want to connect three of Apple's flagship devices together on a daily basis, you can't go anywhere without bringing at least two dongles with you.
