As an old programmer, I read here comments, which reminds me at discussion about the first graphical user interfaces. What was a mouse good for? I could do the same work much faster on my 80x25 screen. Indeed, I think, the new iPad display is an incredible step forward for computer users. The device feels so natural, I forgot almost, that it is a computer. But the the post pc device will left room for desktop PCs mainly for content creation. But I am honest, most time I spend in content consumption and not in content creation.
