When I got my new Kindle Paperwhite a couple of days ago, I couldn't understand why Amazon had made it so that every time, after I switched the unit on, I had to 'activate' it by swiping up the screen with my fingertip. Why not have it start up immediately I pressed the on/off switch like other Kindles, and appliances generally?
Amazon's "Ad-supported" approach would quickly wear thin with me. Mind you paying US$20 to remove advertising seems reasonable - a 15% premium over the free version. It brings up an interesting point. If the lifetime value of ads on a reading device is worth just US$20 to Amazon, which is in the business of flogging stuff online, it says a lot about the what's going on in the world of advertising supported online newspapers and magazines.
