I don't think I've ever had more than that on any of my iPads. I have more on my phone because I like to store music there, but the media I consume on the iPad is streamed.
On a related note, the use of storage as the differentiating price point is also infuriating--it's so cheap (about $1 a GB). Don't get me started on the inflated cost of cellular chipsets, $130 extra for the privilege of paying for mobile data to a specific carrier is a joke.
