I don't care what anyone else says. That is f'cking cool. I've already stated that I intend to purchase an Ipad mostly for movies when I'm at sea, but I can see myself buying interactive books like the one in the video, especially children's stories the kids would totally get a kick out of it. Now the only question is how much will they cost. I've already heard lots of complaining about the cost of ebooks in the Itunes store.
I will say this though I still think the Ipad isn't the best e-reader. Although I base this on my experience trying to read off of my Ipod touch on the bus. If it's overcast it's not to bad but on bright days the glare is to much, I have to turn the brightness up, which helps but it burns up the battery pretty quick. I'm guessing it's the same on the Ipad. The Ipad isn't all things to all people but as it matures it will find it's place or people will find one for it.
I know this statement may start off a bit of a flame war (which I will not particiapte in) but here goes. The Ipad is a game changer. I know there have been Tablet computers made in the past to varying degrees of popularity. But those tablets weren't accessible to the general public. They found homes primarily in the drafting world. The operating systems for them didn't take full advantage of what a tablet could do, they basically just replaced the mouse cursor with a pen or your finger. Apple makes interfacing with touch screens intuative and natural and it's this aspect of the Ipad that changes the game. As sure as the sun rises tomorrow we will see future tablets made by competitors use this formula in there machines. Others will come along and do what Apple has done with the Ipad better, but they will be playing catch up with Apple's mobile devices interface. My 2 cents.
