title: "no activity found to handle intent" Not all phones have Android Market installed
body: <p>Not all phones have Android Market installed, and therefore using intent to open market app fails.</p>
  
  <p>What's the best way to handle this?</p>
  
  <ul>
  <li>Hide this feature if user doesn't have Android Market installed (how would I detect this?).</li>
  <li>Handle the possible error, how (and possibly suggest that the user downloads the Android Market)?</li>
  </ul>
