Yeah, the screenshots look cool until you actually try to use a site with this installed.
First of all, not all of the content on your site is displayed when using this theme. This is made worse by the fact that there is absolutly no way for an iPad user to view the normal website! iPad users are stuck with this junk, so think long and hard before enabling this.
Next, the theme itself isn't all that great. It isn't always obvious what you can click on.
"I see a story, I tap on it, nothing happens."
As a web admin, be prepared to get a lot of questions/complaints from confused iPad users asking where "the real website" went.
Overall the whole thing feels sluggish and not terribly functional. Yeah, the screenshots look really cool, but make sure you play around with it a bit before deploying on a live site.
