Tablet + keyboard cover docking station is just an overpriced netbook. And this combo is on the rise - people want to be able to do real stuff on their devices, when you have so much computing power always with you. And for that you need screen space and keyboard.
Yup. I have not found a better input device than a keyboard for general computing. Touch screen is nice, but when you have to do real work, it's worthless. I don't even want to imagine the repetitive stress syndrome injuries that are going to come from tablets and touch screens.
People think this industry is easy and simple, but they fail to see the injuries even an 8 hour a day computer job causes. And you can't put it on worker's comp either.
Fucked and fucked. That's why I prefer to move my fingers as little as possible (glued to keyboard) and when necessary use a trackball like the Logitech M570 and precursors. Without that, I'd be a garbageman with a bad arm.
