I admire the simple beauty of low tech innovations that remind me of simpler days when I read books and didn't check my emails 99 times a day, like this Booksling from Everyday Innovations. I still have the habit of marking up books as I read (on the rare occasion when I do read), using pens as awkward, lumpy bookmarkers. The Booksling holds your pen outside the book while marking the page where you left off. Nothing more to it than that -- comes in mango, grape or cranberry for $5.99 each.
