That is a pretty small nitpick you&#x27;ve got there ;)<p>It&#x27;s a bit like saying &quot;don&#x27;t they know human flight existed before the Wright Bros.&quot; or &quot;don&#x27;t they know cars predate the Model T?&quot;<p>Of course, but the iPhone (and subsequently Android) presented a gigantic turning point in mobile development, to such a degree that mobile development can largely be categorized into &quot;pre-iPhone&quot; and &quot;post-iPhone&quot;.<p>Pre-iPhone mobile development was a vanishing small industry compared to today and used technologies that are largely completely not around today (see: J2ME, Symbian, Windows CE).<p>So yeah, maybe they could&#x27;ve said &quot;mobile development in the modern context centered around multitouch-centric interfaces using soft keyboards has only been around 8 years&quot;, but that&#x27;s kind of a mouthful, and unless we&#x27;re trying to write an accurate history of mobile software, not particularly relevant to anything.
