You have faster and more accurate typing on a laptop, you have shortcuts for frequently executed commands and actions, you are able to do more on the laptop than you are on the tablet because you are not contrained to a mobile OS or weak performance (one or the other or both is present on a tablet).
I commute into work every day on the train, and apart from looking at the web, playing a game and once watching a video, I have never seen anyone use them for anything else. There are more people using laptops to send those emails early, do some work before they go in or some that was left over, as well as do everything that the tablet users do. I see a guy every day sit down, get his laptop out and start bashing Skyrim.
I maintain that touch phones are worthwhile, you get a larger screen in a smaller package and for something that isn't really designed to do a whole lot. With an interface that is only any good for point-and-click applications they are great, for doing anything other than pointing and clicking, you can not beat a mouse and keyboard.
Intel have broken into the smart phone market, if AMD do break in they are once again going to have too little, too late unless their chip is super powerful or it has incredible efficiency, which I honestly can't see with them competing against ARM and Intel who have both put huge amounts of time and research into their products and with the latter having a near monopoly and a hell of a lot of experience
