It looks well inconvenient! The iPhone is not a small phone by any means, imagine carting that ****er around! You'd be better off with a laptop/netbook—similar size but way more functionality.
Plus think how expensive that'd be… A paper is <Â£1, and you can fold one of those up and take it wherever. This thing is rigid and will cos about 500 newspapers.
unless it has a stylus and enough power to run photoshop etc (or a lighter version of) I can't see the point in an enlarged ipod touch (its meant to run iphone os-x). If its aimed at purely a web tablet (ie viewing the web and using cloud computing) then surely the likely to be cheaper crunchpad be a better option (under $400 at present) as this is its intended purpose plus some media playback bits.
If I wanted an ebook reader (ie kindle) then using a tft type display is just wrong the whole point of eink was batterylife and being better for your eye sight (yes I know theres a hybrid eink/tft) and you can get an ebook reader for around Â£100
I wouldn't exactly say its revolutionary, its simplification to the simplest form which is easy when all you support is one product (the ipod touch is the same hardware basically), its fundamental that a product that supports more than one hardware configuration is going to be more complicated. Look at the palm pre, its (arguably) the next best phone to the iphone and what does it have in common, one product (well 2 if you include the pixi but its not out yet)
Just look how long it took them to implement some of the features that were standard on my old p900 (and the p800 before it) and to be honest apart from gps, wifi and 3G which wasn't around in a mobile back then there isn't a great deal of progress between the two in my opinion. Plus I like having a stylus on my touchscreen mobile.
As to the app store, there have been earlier versions but none with the 'sales power' of itunes.
Why are people acting as if those pictures are the final designs of a possible tablet? If you look they are each a different design. I hope it doesn't look like any of these, they are awful.
And the whole idea of having it as a "print player" (whatever the hell that means) is stupid. Having a device like that with the sole purpose of having it display newspapers, magazines, etc is ridiculous. Apple - while simplicity is part of their MO - wouldn't limit themselves in such a way. They'd develop this to allow their users to get the most out of their product like they had with the iPhone. I wouldn't be surprised if there was something far more complex if it actually arrives.
