Translates to: Nobody knows, there is no evidence, people are wishing for the ipad to become the computing device of the future, but dont know how that new computing future could be different from tomorrow.
But, since apple did a great marketing job, as always, you are not alone. There are hell of a lot of people who will buy the ipad, but don't exactly know why. I know a lot of people that want an ipad, but when i ask them what would be so great about it, what would they do with it, they don't really know, they just think it's awesome. Which in my oppinion, is a result of good marketing (and neat design). It looks neat, the whole world is talking about it, apple is cool, so i need one too!
This discussion is somehow the same, but discussed by geeks: It's cool, it's easy to use, those dumb other 99% of computer users will need this, but i don't know why. :)
