title: Is it much harder to write mobile web apps in Vaadin without TouchKit?
body: <p>The question says it all. If I don't use TouchKit, which is only free for open source projects, what will be the difficulties I'll likely encounter trying to develop a mobile version of my UI?</p>
  
  <p>I'd go about it via the <a href="https://vaadin.com/wiki/-/wiki/Main/Creating+an+application+with+different+features+for+different+clients" rel="nofollow">UIProvider</a> facility.</p>
  
  <p>Many thanks!</p>
