The success of this kickstarter project shows that there's no real use case for tablets except surfing/reading/consuming/procrastinating on the sofa and thus, people want their keyboard back—anything else can be done more effectively with a computer/notebook and/or a smartphone—there's just no room for a third device between notebooks and smartphones. Don't get me wrong I appreciate all the innovations in application and OS design (iOS and the lean ARM architecture could replace x86 designs) which came with tablets but I doubt that tablets with their clumsy form factor will take over the world.
I still don't get the success of these devices. It's so much more convient to type, to keep the finger movements small (with a mouse or trackpad or a small touch screen in devices like smartphones), to have the right viewing angle without holding anything warm or using ugly extra stands. Only when surfing around and reading sites I see a real benefit but then again: moving fingers to 'click' links or to go back is so much more work compared to a small notebook like the MBA and I spend the entire day with the Internet anyway, I have to force myself to do something else in the evening—I don't want to meet again the Internet, Facebook and Google when I should go out, meet friends and family. Or I just want to watch a movie and even this is totally cumbersome with a tablet (compare this use case again to a notebook like the MBA, I just put it on my lap lying in my bed and that's it: no stand, not getting warm, always the right viewing angle, I don't have to hold something).
Again: if you disagree reply instead of voting this post down—this isn't gonna be a flamewar—I just want to question, is there really a post pc era coming where tablets replace computers (I would rather guess that smartphones and not tablets will fill the gap and could get the main distribution channel for software).
