Pottermore announced on their blogthat the site was now compatible with tablets:
Being able to use Pottermore.com on a tablet device has been a popular request by members of the Pottermore community, and for this reason, we’re excited to share the news that the entire website is now compatible with leading tablet devices!
Not only will the new interactive Moments be at your fingertips, but you’ll also be able to touch and tap to duel other wizards and brew magical potions (make sure you don’t get your fingertips too close to the flames!).
The problem with this news story is that I'm not seeing any difference between the site on my laptop and on my tablets. Furthermore, in its current state I would not in anyway describe it as mobile friendly. Yes, you can use the site from a tablet but you're still using the regular website.
Am I missing something?
