I'm disappointed and hopeful at the same time.
I think it's a little shortsighted and superficial to call this simply a large ipod touch. Yeah the homepages look the same, but the apps, just the few that were demoed, were much improved. Calendar, email, safari, photos, maps: all these were vastly different and more functional than those of an iPod touch. Imagine what other devs can do with their apps.
That Courier demo, which was awesome, can nearly be replicated on the iPad. Journal Apps, photo editing apps, video apps, etc can all be just as improved as the demoed apps.
That said, my disappointment lies in the fact that this is a docked device. Even if all I want to do is browse, email, music, edit/organize photos, game, and journal (all the BASIC things, that 90% of people do), I still need another computer. I can't sync my iPhone or iPod to it (that's a biggy!), I don't fully know if one can organize iTunes with it, and I don't know if one can organize photos (though there is an accessory for camera connection).
So I can't recommend this to my parents or even my girlfriend or other people that just need a computer for these basic things, which is most of us, because you still need another computer. And this confuses me because, when talking about the price-point, they said the wanted everyone to have one, but none of these people will need to get one because THEY STILL NEED A LAPTOP.
Fortunately, the fixes to make this a perfect, stand alone device that covers 90% of people needs, are simple: let people sync iPhones/iPods to it and include even a simple version of iLife that includes (if you can't already do it) the ability to organize music and photos. Done. That's it.
Though, I still need the ability to download torrents...
Maybe, and most likely, Apple doesn't want this to be a replacement for a mac but that's kinda what they seemed to imply at some points.
You make a good point. I wonder if you will be able do OS updates without another computer. As long as you are content with getting all your content from iTunes I don't see why you would need to dock it other than updates.
Maybe they will allow external cd or hard drives to connect through the dock and import into mobile iPhoto and iTunes in the future though...
It seem seems like a moot point though since I don't know anyone (although I'm sure there are some) who doesn't have access to some kind of computer and iTunes to set it up...
