I think it is obvious by now that tablets without the real keyboards are actually just the reading and entertainment devices. They are not a "serious" stuff by any means. Same goes for smart phones. So it all depends on the target market. If we look at the landscape, we can see that we have practically adopted tablets as an add-on device over TVs. Sure we're reading conveniently without flipping hard pages but is there a significant and life changing gain? You can use your phones as a GPS so you don't get lost. Big deal. It's not like people never ensured that they have directions before heading out to unknown locations. What else have we achieved via these handheld computer devices? We can take pictures and videos so we don't have to carry additional cameras or camcorders. Is that a gain? We can ask the camera manufacturers. What else is there?
