If the Tablet is so good I'll still be using it 20-30 years from now, then it will be a bargain at even the $1000 price point.
While I was answering a question about can it fit in a pocket, that's not necessarily where I would store it. Apparently, this is something I'll be carrying around in one hand, consuming all this fantastic print media I don't buy now converted to digital print (that it will make me feel compelled to buy because it is so much more convenient, or it unclutters my home, and so on).
In reality though, I would probably carry it around in my travel bag... with my laptop... as I don't have any needs to have a wireless phone with me everywhere I go... just very occasionally when other options are unavailable to me. In that case, I would retire the tiny iPod and add this 7" iPhone/iPod replacement (that will also have all these fantastic new features beyond the iPhone/iPod that we just could not live without). Personally, I'm just hoping for a bigger iPhone at a good price (because the current iPhone is just too small for my tastes). If it does some other great stuff, that's bonus.
