You can attach a keyboard and some other peripherals, I gather. Believe it or not, no matter who the target market is, people ARE using tablets to do graphic design and other work stuff. Basically, we're moving toward more digital access everywhere and away from centralized work/shop/socialize (as in, fewer things keeping us in centralized offices/meeting places), and that means smaller computers are going to be pushed to their limits and things like "Ubuntu Touch" popping up until the mini devices are truly easy to use for most things because they interact freely with any non-portable machines that must stay in use.
Just because tablet sales have taken off doesn't mean you need to go buy a tablet or that a tablet will help you do what you want. Tablets are to aid mobibility. Why do you feel you need a full size keyboard and dvd burner with a tablet?
