I am so incredibly sick of hearing people make these speculations. As we speak I’m writing this comment on my iPad 2, I wish I was in the other room on my desktop. Logging in to post this comment via Facebook is reason enough for me to want to be on a different device. The fact that advances in ARM powered devices are currently out pacing traditional computers doesn’t really mean very much. The desktop computer will surely see another period of rapid performance increases. Besides that this idea of using a tablet with an external keyboard is just plain stupid. I have that and I also have a MacBook Air, I strongly prefer the MacBook Air. Why would I want my keyboard to be detached (just makes it a pain to carry) when I can have it connected to the computer? Not to mention touch screens will never be nearly as effective as a mouse, I find myself frequently deleting an entire sentence because its easier than actually selecting the position I would like edit. The mobile and desktops markets aren’t in equilibrium right now, they’re going to move back towards desktop dominance.
