I remember when a friend of mine got his first i-pad. We're both developers and he said he could do some basic editing with one of the included apps. First thing I thought was, "Oh yeah, I'm going to write code on a 7" screen as opposed to my 23" monitor."

The PC isn't dead and it won't be for a long time. Although there are a lot of lines being blurred between devices (tablets vs. smartphones vs. laptops), there's still a TON of people working at large corporations who you'll have to pry their PC's out of their cold, dead hands.
