edit: for the record I think this limit is stupid and the biggest flaw of the Air. You're right that other than that, it's a damn near perfect daily driver.
I couldn't agree more - I was shocked when I discovered the Air can't natively drive two displays, even with many docks. The only real solution are things like that kensington dock's display-over-USB hack which is not as reliable as a native monitor connection in my experience, and requires additional driver software on your OS :(
I just took it for-granted that every laptop in this price range on sale today will by and large be able to drive two external displays, but nope!
I ended up using a "double wide"/32:9 style monitor - the Samsung CRG9 - these 32:9 panels can be had in 5120 x 1440 resolution, which is exactly the size and res of two 27 inch 1440p panels side by side but in a single display. Works great on the Air, although its not a super cheap option.
Which comes with drawbacks. Video is sent out compressed over USB protocol which requires CPU cycles, more resolution + moving images = more CPU grunt required. Plus there is the risk some update will break the driver making your dock useless.
I think you're right, but the irony is the segmentation isn't working - in my experience no customer notices this drawback on the Air until after they've bought it. Everyone (quite rightly) assumes a 1000 dollar+ laptop will probably drive two displays in a pinch.
I don't know anyone who went "Ah! only one monitor support!? I better move up the range to get that 2nd display support..." etc. You would really need to get into the weeds on the spec sheets to notice ahead of purchase.
I actually find many more people doing the opposite - choosing to move "down range" to the Air for the form factor, given it still has a great CPU. These power users who choose based on the great form factor get hurt the worst on this.
The M2 MBP also can only drive 1 external display. The M2 Pro and M2 Max variants can drive more. Apple only put two display controllers in the M1/M2 chips which is why they support so few monitors.
It's still for market segmentation but there is a hardware reason.
Check out the DisplayLink stuff. I think it works pretty well. I even devote one DisplayLink screen to security cameras (4-6 640x480 cameras at 15fps). I also use that screen to play YouTube videos, if I'm following along with something
It handles it just fine at 8-10% CPU usage on an M1.
