I don't think you should discount different form factors being useful in different situations. Tablets are great for consuming content, and creating certain types of content, but as much as you can write a novel on one, a real keyboard is better for writing one. (yes I know you can buy a keyboard dock, but that sort of misses the point, doesn't it?) And as much as I can play games on a tablet, unless it's a very specific niche where the gameplay revolves around your input method being a static slate of glass (e.g. Fruit Ninja, arguably Angry Birds) having actual buttons for input is better for gaming. So I can totally see 'normal' people just owning one device that does everything OK-ish (but at least it does everything) and I think for all 'new' normal people that's basically happening, but I really don't think you're going to see other form factors go away. Authors still want to type quickly, gamers still want actual controls where they can exercise muscle memory, and I hackers still want to be able to tinker with their devices and build cool new shit.
