Emojis: I'm with you. This seems dumb but I'm optimistic that people will find clever ways to use the screen. Even if it's just pushing away moronic "toast" style notifications off the important real-estate.
USB / dongles: In two years, almost all peripherals will be USB-C and C-to-A adapters will be tiny and cheap. USB-C will be the new Thunderbolt and it'll end up being more convenient. I'm looking forward to sharing displays with ultraportable Windows machines and chromebooks using USB-C.
In two years.... so not Today? Because they replaced the USB-A ports today... and not in their 2018 MBP.
Besides, the old peripherals won't disappear within the next few year and most of the world can't easily switch to type-C anyways - since they literally have no money to buy modern technology.
USB 2/3 is "good enough" for too many things to fade away. Any notebook should have 1 type-A port for convenience.
