Booksling

This is a nifty little invention, and while it's not a fancy electronic gadget, and it won't change the world, I bet nearly everyone could find a use for it. The Booksling wraps around the cover of any book and provides a handy penholder and bookmark all in one, so you can always keep your place and your writing implement close at hand. $5.99 USD. Plus, enter FREEPICO at checkout to get a free PicoPad. (Via Gizmodo.)
