Tablets will eclipse laptops and desktops for the same reason people eat dinner in kitchen/breakfast nook instead of the dining room. They are lazy and will make do with what is in front of their face.<p>The iPad, because of its form factor, follows you around the house. It's sitting on the kitchen counter. It's on the arm of your deck chair. It's portable in a way that not even laptops are.<p>It's the book you read because it happened to be on the shelf at your parent's house. It's dish you order at your husband's favorite restaurant. It's not the most powerful computing device ever to grace this planet, but it's <i>there</i>. It's immediate.<p>And maybe for the few of us who have a compelling need that forces us onto the laptop (development, design, typing, etc) maybe this is less true. Because once you're on the laptop, the immediacy of the iPad is sot of cancelled out. But for the vast majority where the iPad offers an OK version of everything they need, it will take over.
