Because it's indicative of systemic failures. Why waste space and add bulk to carry around ports you never use? Did you think adding those things come at no cost?
This is why people say less is more.
Almost all MBA owners I know carry a dongle with them.
Correct, mine weighs about half an ounce and I think I have used it maybe twice in the last 7 years. To be honest, this comment is going to prompt me to go find it in my bag and toss it.
Great so you can always add a dongle if you need them.
Now how do I get rid of extra ports if I don't need them?
Because maybe I do use ports and don't want to have to use a dongle to plug stuff in. Even apple realized their excesses and brought some more ports back. They've totally lost the plot on devices
So why should I have to carry around extra bulk for ports for your convenience?
