An old AlphaSmart can be picked up for a few hundred dollars on eBay. Kind of a clever distraction-free text editor.
I picked up a couple a few years ago. Pretty clever in that, one way it transfers files. You connect the device via USB to a functional computer and ready an empty document in your text-editor of choice. Push a button on the device and it sends the internal text as though from a USB keyboard to your computer: speed-typing [1].
