This was IMHO a truly solid idea, albeit ahead of it’s time in many ways. I bought one and it still works, though the battery is only good for about 15 shots. I agree the camera quality was mediocre, but the ability to literally have on boards apps to view and lightly edit was great.
It was my go-to for trade shows and demos.
I’d love to see a new version with updated internals and S-Pen support.
