I spotted this at a nearby table in the Coffee Zone last week. I couldn’t resist interrupting the gentleman to inquire. The AlphaSmart 3000 is a word processor with a tiny LCD screen. Just 4 lines of text. You can call up other documents using the gray keys. There’s a USB port for moving your stuff to another computer.
According to the owner, a few AA batteries gives him 700 hours of hunting and pecking. I’d really like to meet and interview the person who conceived of this device.
