This has been a long time coming. My company owns a Jamboard (the hardware). They were selling it hard when we bought it. We got to use it for a year before the service contract expired. All the major features stopped working, there was no way to renew online and the salespeople were no longer answering phone calls or emails.
So now we have an expensive, heavy albatross on our hands. Really makes you want to avoid depending on Google for anything again.
Have one in my living room: 100 lb bright red deadweight. Does get excited questions from guests though!
I'm pretty intimately familiar with Android hardware devices having launched some myself and planned on creating for some sort of "jailbreak" (really you'd want to break into the Jamboard MDM system, not the OS) but it hasn't been a priority.
You can pick these up for cheap sometimes when people realize it needs a $1000 a year license to function...
I've hit a related problem with my interactive display from A.G. Neovo.
For use as a whiteboard, I really want low latency from (a) dragging the stylus to (z) the display catching up with what I've drawn.
Their built-in Android app is great in that regard, but it's proprietary so it's not good for collaboration.
Unfortunately, there's much worse input-to-update latency if I use it as an external touch display, or if I use it's built-in Chrome browser with whiteboard websites.
Without the ability to root the device, I can't really investigate the source of that extra latency.
And it's not Google Play certified, so I can't install native whiteboarding apps from some the well-known vendors I've tried. (Those vendors require installation via Google Play.)
