Retro Gadgets That Have Gone High-Tech

USB Typewriter — Remington Portable ($550)
The USB Typewriter connects via USB to your PC, Mac, or iPad and serves as a fully-functional keyboard … whose keys are incredibly loud and sure to annoy even the most patient coworkers or loved ones. (Yes, you can order one with the keys silenced.) You can also order a DIY kit to convert your own old typewriter, but it looks complicated enough to be something you may want to leave to the pros.
