Anyone with a career in the AV industry will tell you that "air" is code for "fool who was sold on Apple propaganda".
Two ports and no internal hard drive a a recipe for disaster.
Off the top of my head - quick scenario:
you have a business presentation at the company's annual meeting.
You go to your local convention center with your presentation done and ready. Its saved to the cloud.
You go to the lectern and there is a cable with an HDMI adapter. This connection goes to several video systems - some display your computer's desktop to all of the monitors, projection screens, video walls, etc. Some go to the downstage monitors in front of you so that you can do your presentation without having to have to hover over your computer. You have a presentation advancer for your computer. That's one port. You now need to find an adapter to go HDMI. NO, it is not the AV company's responsibility. Oh shit! You don't have one! A nice technician loans you theirs. It is a USB-C to HDMI adapter. Saved! Now all you have to do is download your presentation from the cloud and you're set. You get ready to logon to the internet and realize that you can't! The internet is running slow as hell because everyone else in the ballroom that you're in is also logging on and using the internet. "Oh, shit!" "What to do now?" You call the engineer/technician up and tell them the problem. They give you the rundown: "Do you have it saved on a thumb drive?" "Nope, the file is too big" "Okay, we have a hard line for presenters" "Do you have an adapter with an ethernet connection? "No." "Maybe we have one…I'll check" "One of our techs had one that they are willing to loan you for your presentation. "I need to unplug one of these to use it" "That one goes out to the screens" "This one is my clicker! I can't advance my presentation without it"
"I'm sorry, sir. I don't know what to tell you."
Fucked. You're stuck standing in front of the computer, advancing it by hand. So much for audience engagement.
Let's say you get the presentation up and something happens and your presentation goes down in the middle of it. Let's say the internet goes out or gets too bogged down with other connections.
If you had PORTS, you could also have an external hard drive with you with the whole presentation on it to run it from. You've only got two ports. You're SOL.
If it were a pro, you'd have an internal hard drive.
Now, I just came up with this off the top of the dome. There are a myriad of other reasons I could come up with.
This is a fine computer for at-home work that is not dependent on connectivity of any kind.
So, FOH with your 8k video if it can't go anywhere. The fact that people even play 4k videos on tiny ass screens shows how ignorant most people are about the purpose of the tech. Higher resolution is so that you can show videos on larger screens without aliasing or pixelation. Unless you're using it for gaming (not a professional use unless you work as a game tester), it really doesn't even matter. "Prosumer" specs are mostly for the marketing department to pump to consumers so they can feel like they are getting the same thing as the pro product but saving money. Congratulations, Apple marketing team. Looks like it works.
