Make one that is less expensive and more accessible
Related: Don't cram a bunch of pointless tech inside of it. Just give us a screen in a nice enclosure, especially now that you've done the work to allow iPhone as webcam usage.
Also, a lot of environments don't even allow webcams at all -- don't eliminate them as potential buyers by jamming an Apple TV, webcam and mediocre speakers inside the thing.
Add a 2nd input also please.
Some of us have several computers/devices.
An overpriced screen that connects to one thing at a time ... sucks
Include a height adjustable stand as default
Seriously, some of this is absolutely table stakes stuff.
This isn't as hard as you keep making it Apple.
