I've been using my Motorola Xoom as a bedside alarm clock pretty much ever since I got a dock for it 4 years ago. My only annoyance with it is that even when the screen is dimmed, it still emits a fair amount of visible light, owing to the older TFT panel. Eventually, once it breaks, I'll have to replace it.
Anyone have any experience with using an Android tablet as a bedside alarm clock? Any thoughts?
