If you can afford to pay $2800 more so people can't see what you are doing on your iPad, you are probably in the minority. It's really cool, but really expensive. I see this as like the Macintosh Portable.
Also, there's a good chance that devices like this have a strong future. Just like you could argue that a Macbook is a descendant of the Macintosh Portable, the fact that lots of people own macbooks doesn't mean the Macintosh Portable was a success.
That "just" is doing a lot of work there except I think it's WFH and on a Netflix binge.
