Unless you've been living under a rock, you've heard about the Apple iPad. The iPhone big brother arrived a few weeks ago, and Apple has sold a huge number of devices already.
The iPad is already a success, and as a device for consuming information it's really great.
So how does this relate to your reality as a Joomla user? In short: You need to make sure that your Joomla website works on the iPad. And not just that it works. It should be a delight surfing your website on the iPad.
