Oh yeah, I remember reading about the AlphaSmart somewhere! Though it is quite different from an ordinary-keyboard-looking spying device that I tried to describe in my original comment. The AlphaSmart feels like more of a digital typewriter that just had a really primitive data transfer method
They have, but all of them are "personalized" attacks - as in, a malicious person needs to install these on specifically your computer, without your knowledge. What I was talking about is some kind of device from some noname Chinese manufacturer that presents as harmless, but actually sends off some additional data back home
