Unless you're part of the Macbook's target audience, in which case you don't need the dongles.
Don't get me wrong. I'm not in that audience either. I'd buy a MBA. But just because I'm not a member of the target demographic doesn't mean I erroneously assume that there is no target demographic, and that Apple must be stupid for releasing a device that appeals to literally nobody.
Because assuming that would be narrow-minded and ridiculous. I am not the only consumer on earth.
Could be, but do you really believe this 'audience' really will not need any dongles?
Do you know of any users who will never need to plug-in a USB Flash Drive, or External Hard Drive, or connect to an external monitor or TV, or connect to a portable printer that it's not latest generation?
And finally, there's a rumor that Apple may reduce the number of ports on its other portables. I really hope this is not true.
There's more to choose from, but the choices are becoming more and more narrow. Now you must choose between a MacBook Air or a MacBook Pro. Before, the MacBook was the least expensive portable choice.
If you want the new Force Touch Trackpad, your only choice is to get a MacBook (unless you want to carry a separate trackpad), or wait for new MacBook Air and/or Pro releases that will include it.
in the past, the MacBook Pro was the portable with the most features and functionality. Starting with the number of external ports to the higher-end GPU. Now, unless you pay the big bucks, you will be stuck with the Intel Iris Garbage.
Providing many choices may seem like a good thing for some consumers, but in reality, most consumers get frustrated when they have to decide between several options, becoming a deal-breaker.
And when some of these consumers compare the MacBook with the new portable 'clones' (which have more connectivity ports), they will think: "It's compatible with what I already have", and decide to get that instead.
