You're wrong. What they want literally makes the MBP not usable for many others, whereas what I (and many others) want doesn't affect the usability/performance of the MBP for anyone.
Exactly. If you have a MacBook with two ports and you use only one, the mere presence of the second port has no effect on your life. But if your MacBook only has one port and you need two then it's an actual inconvenience. It's not like we're paying per port of like they are adding weight. It's not cars where everyone's insistence to have cars that can do everything at once leads to some SUV monstrosities which are compromised in many ways, it's a laptop where having literally a modicum of extra functionality has no negative sides whatsoever, I guess apart from people on the internet saying they don't need them so they shouldn't be there.
We're not paying per port, but adding more ports surely adds to the BOM, which influences to total price.
And I agree that adding one port doesn't make the device noticeably heavier. But I thought we were talking about adding multiple I/O ports, since that's what the article says and other comment are talking about adding multiple USB A and C ports, MagSave, an SD slot and even an hdmi port. Adding all those ports will increase the size of the MacBooks.
I'm not saying it's wrong to want to have more ports (I wouldn't buy a notebook with one port). I'm saying that it's strange to call people egotistical for wanting fewer ports while failing to see that adding ports has consequences other people might care about.
