Actually you are wrong. Reason is the guy made that video for his subscribers, they perfectly understand what he does and why he has six monitors and got what he was saying in the video. Mac Rumors have taken the video and stuck it on the front page, then made some random story about it, I doubt very much they asked the guy to use his video, and so now all you lot are complaining about him when the video was NEVER intended to be posted here in the first place!
If a random You Tube video is posted here it is up to you to go and find out why he cannot show his point with his work AND it's up to the Mac Rumor writers of the article to make that clear. It's like eavesdropping then complaining as you only overheard half the story.
The video was made for his 40 thousand plus subscribers, NOT the Mac Rumors website!
No need to start shouting. I understand that. I'm watching "Desk Tour and How I Use My 6 Screens" now. If he wants Apple to address his use case, though, he needs to make a case for having single windows spanning multiple monitors on an optional independent-space model. I doubt anyone who can do anything about it is going to watch his channel to understand his concern.
