I'm with you on the touch screens. I just don't find that they make me any more productive..in fact I feel it's just the opposite.
Had this device really been different from an iPhone, I might have been a little more excited...but like you said, it's just a giant iPhone. I just don't see much practicality with a device like this. It's cute at first, then just a pain to lug around with you. I don't want something that big.
A friend of mine and I discussed figuring out a way of making it a belt buckle and then could have a slide show display various images like Ford Logos, or giant bass fish or something. I'm downloading the SDK right now...the app will be called iBuckle...keep an eye out for it.
I stick with physical books as well. This way I can read them when the plane is taking off or landing. And I can let others borrow it, I can sell it back used, or I can lose it and only be out a few bucks.
