It&#x27;s not really fast, but it&#x27;s not a second, either. Just ran a quick test on a kindle paperwhite, repeatedly paging after I saw the page refreshed. 20 pages in under 14 seconds, and there was definitely lag time between the page being refreshed and my finger tapping again.<p>That said, the page turn lag bugs me, too.  It&#x27;s better on tablets&#x2F;phone.
