I like the boox devices, (they run a mostly stock Android that you can use the Google Play store and download whatever you want to them. Switched over from my Kindle a year ago and it's been fantastic)
I was using it with facebook messenger video chat, accessed through messenger.com. I don't know if it works with all video sources, yet I can't see why it wouldn't.
My wife and I have been subscribed to acorn.tv for several years instead of Netflix. It has many eminently watchable shows, especially Poirot and Foyle’s War, my favorite.
Excellent news. It would also be helpful if we could also get (missed) call notifications on desktop. Right now if someone calls and I don't have my phone with me, I don't see their (missed) attempt on the desktop.
