I have no love for Google, but I&#x27;m not sure how you somehow group &quot;touch based UIs&quot; into &quot;proprietary services&quot;.<p>There are plenty of great apps on mobile devices that support open standards. The whole point of an open standard is that you have the freedom to choose how you consume the data - be it a terminal&#x2F;shell client, a desktop GUI client, a mobile &#x27;touch&#x27; client, a web client, whatever.
