While my 13" MacBook Pro rests on my knees, I can smoke with one hand, hold my coffee in the other hand, and read this article at the same time. I started it in the kitchen and finished in the bedroom.
How is iPad going to make my life better? Will I be able to do 3 things at a time with it? I suspect one hand will always be busy holding the thing. It will get tired, let alone that I won't be able to smoke and have my coffee and read an article (and always have the UNIX shell at hand) at the same time.
This seems like an iPad killer in the bad sense to me. I'm sorry.
