These two features—wireless delivery and the E Ink screen—proved to be two of the keys to making the Kindle great. Wireless delivery meant that customers could search, browse, buy, download, and start reading a new book in under 60 seconds. The E Ink screen’s paper-like display meant that, unlike with an iPad, you could read by the pool, and its low power consumption meant you could read throughout a 12-hour plane flight without worrying about the device dying on you. We take these features for granted today, but in those days they were unheard of.
