1. have you personally used it as an e-book reader? If not, how do you know it's not a good e-book reader?
2. have you personally used it to use email? If not, how do you know a netbook is that much better? If I have a lot of email, the last thing I want is to type on a netbook keyboard.
3. The pricing is right in line with the iPod touch.
1. It's not e-ink or something 'flat and matte'. I tried e-books on various MacBook, MacBppk Pro and Air screens. They cause eye-strain and they are useless outside. I'm not just talking about the extra-mega-hyper glossy screens. I'm also talking about screens that the Airs had over the years or the screens of the white plastic MacBooks.
2. I used email on an the above and on my iPhone. Reading emails is sort of OK, but you cannot seriously expect people to start using the virtual keyboard without any difficulties and remorse.
3. Well, if we take the screen size into account as a major cost. But it's not. With most manufacturers, a 15" laptop is cheaper than a 13" one. Not with Apple.
But about the iPod Touch vs. iPad pricing... I know, the performance is different (but there are the more expensive earphones included with the new generation of Touch), but when comparing storage space, a $300 price difference emerges. THAT IS A LOT FOR NOT A LOT OF EXTRA FUNCTIONS. In fact, is there anything apart from the larger screen?
Besides, size matters in computing, so in a way small computing power is already at a premium price. On that principle, the iPad's price SHOULD NOT be in line with the iPod Touch, as you said. It should be much closer.
