The problem with making my laptop work like an iPad is that the laptop is a general purpose computer and the iPad is not.[1] The genius of the iPad was that it was a specialized device built for a single purpose: consuming media anywhere, anytime. It has long battery life, sunlight-visible screen, and does not require mouse or keyboard. It is very good at its purpose -- you can use it as a book reader or movie viewer while riding a bus, sitting in a park, etc -- and it sucks for anything else (e.g. anything that requires typing more than a few characters).
My laptop, on the other hand, was designed to be an all-up computer that could be used anywhere that there was a flat surface, but mostly indoors. I can use it at home, at the coffee shop, etc. It's also fine for consuming media as long as I'm not in direct sunlight or away from power for more than a few hours.
So. What exactly am I gaining by adding these iPad features? Sure, I bet they're handy and I'll probably learn to use them. But I can't help but think that a bunch of guys as talented as Apple could have produced something really impressive in the time they took adding these iPad features.
