I agree. Criticizing kindle reader because it lacks desktop functionality is comparing apples and oranges.<p>But we are talking smartphones here. If you claim that smartphone is no more than kindle reader with ability to call, then why is it <i>smart</i> -phone? How can apple market it&#x27;s phones with &quot;25 billion apps downloaded&quot;?<p>And eventually could you insist that owning a smartphone is somehow essential for modern life? You could just settle with dumb phone, books and old walkman. If smartphone is not essential then you can&#x27;t make apps with the assumption that &quot;everybody will have smartphone soon&quot;. If you don&#x27;t assume that, smartphones are doomed to be a just luxuries.<p>Then stuff like &quot;you need to optimize your website for mobile&quot; is pretty much like saying &quot;we need to optimize our streets for roller skating&quot;.<p>If you think that, I would honestly agree. I think smartphones are just a fad. But I would not bet on it.
