Last month while sitting in a cafe, my friend Andrew showed me an article about a quirky new E Ink device that was launching (we're both huge fans of the technology). It was cheap enough to be impulse purchase material, so I went to order it. And on the checkout page, something happened which has literally never happened to me... ever... I saw a "you might also like" style sales pitch, and the product was actually so compelling that I bought it 😱 The company was basically nerd sniping me.
