Daring Fireball has some Macworld Expo 2007 Predictions. I agree with him for the most part, though the sub-compact notebook, not saying "tablet" or not, just doesn't make sense to me. Of course, I don't see a purpose for the Microsoft ultra-portable "origami" (or rather, "ori-where-did-that-go") or their tablets for the mass market beyond a couple of very specific applications either.
Maybe not "agree" with the predictions as much as "yea, I can see that" anyway. We'll see in an hour or so I guess!
