-        this doesn't seem to work. i get only browser and IndieBound reader as options on my phone. perhaps I should recommend IBReader instead?
+        If we're going to be providing mobi as the norm, let's not bother with these instructions.

If you've set up your Kindle email address at Amazon.com, you can also email it to yourself using the "Connect/share" button, without needing to plug your Kindle in.  Calibre will walk you through the process of setting up your Kindle email in Calibre.</li>
