This was partly the reason that lead the former Tumblr employee to create the reading application, Instapaper. The minimalist app, which strips all "toxic aspects" of online reading (web advertisements, cluttered formatting), promotes the stated goal of "attentive reading." The idea is that to be focused, all digital distractions must be absent from a reading device. In fact, "the fewer productivity tools a device has, the better it works as a reading machine." That's one reason why Amazon's Kindle is Arment's favorite device for cutting through the clutter:
One reason I love the Kindle, more so than the iPad, is that on the Kindle you can’t do anything else but read...It’s the best because it does the least. It doesn’t even show a clock.
