Exactly, the very first iPhone didn&#x27;t even have installable third party apps. &#x27;Why didn&#x27;t they sue webaps&#x27; ignores the fact that it was tried right from the word go and in a fight with native apps that was skewed in web apps favour, they still lost massively.<p>Chrome OS is of course an attempt to build an OS entirely on HTML and Javascript, but you don&#x27;t see it on phones because the memory, CPU and power requirements are too high. Eventually these problems will likely be solved, FirefoxOS was another attempt, but if we can&#x27;t even do it right now there&#x27;s no way it was a viable option back in 2005.
