Like this one about the iPod.
Or this one about the iPhone.
The iPad is an answer to a lot of questions that people haven't asked. Never mind the tech blinded savvy cynic end users that want the next heavy processor ram battery brick portable multitasking workstation and as a result see the glass as (less than) half-full because the iPad sucks at being that kind of computer. A hundred years ago, these sorts scoffed at motor-cars because they wanted better horses. And these sorts will scoff at people who "lemming-like" stand in uberlines to buy an iPad.
Well, they'll scoff until they're compelled to buy one next Christmas for their wives, kids and their kid's grandparents.
The iPad isn't a computer. Nor do think it's designed to be one (any more than the iPod and iPhone). Rather, it's a complimenting - not a competing - device. It's something else. And this is important if you're Apple (or an Apple shareholder) and in the business of selling hardware. Apple isn't asking their users to choose another computer. Their asking their customers (and more importantly - a lot of new customers) to approach the internet from another point of view. So I suspect when people finally get to experience one - they'll realize it's not a computer and not meant to be. But it won't matter. It's something else that's very compelling. And they'll probably want one.
I think it's a vertical integration of a lot of devices: handheld gaming, DVD players, web browsing and email, etc.
I think it'll be popular with kids; look for books, homework, painting/drawing, school and learning focused apps and movies in the backs of minivans.
I think it'll be popular with teenagers as a collaborating, communicating device at home and school; media, music, video, Facebook, blogging, idea sharing, idea presenting, note taking and beats the heck out of carrying around a backpack full of books. And because it'll be a compelling status symbol.
I think it'll be popular with parents and their parents. People who don't want or need another laptop. But still want to be able to "get to their stuff".
I think it'll be popular with grandparents that don't want or need a net book - but want a rich, portable, user friendly, media web based experience. Plenty of on-board storage and plenty more in the cloud.
I think it'll be popular with road warriors: email, reading, podcasts, video, note taking, ideating, twittering and presenting.
I think it'll be popular with developers that want to create cloud-based thin clients and purpose focused tools.
I think it'll be popular with Apple share holders.
The iPad isn't a computer. Nor is the iPod. Nor is the iPhone. And no one else is making anything like it. And like the iPod and iPhone - other people will try. And just about the time they get it right (maybe...ahem...Google Android...cough) Apple will have come along and redefined the paradigm.
That's my prediction.
