> I see nothing ridiculous about it. Most PC workers are not glued to the keyboard/mouse - certainly not the keyboard.
Oh perrlleease... If you're sitting coding, writing documents, planning projects, analysing data... you know, work, you're spending the day with your hands rested on the desk, fingers on the keyboard and using a mouse to move the various windows around the screen and focus on the *accuracy* you need to point at elements of a high-res screen.
Sod your idea of a mouse free interface; you'd end up with arms like Popeye and aching shoulders by elevensies. It's bad enough trying to raise your arms to point at the screen without the additional issue of *accuracy*. Then there's the issue of "resetting" your hands back to the keyboard: with a mouse, one moves one's hand to exactly the same place on the desk and use your fingers to manipulate the mouse, therefore one gets "muscle memory" to return your fingers to the keyboard.
OTOH, if you're flinging birds at pigs then there's no doubt a touch screen is better, 'cos Angry Birds is crap on my 27" Mac screen. But I suppose Angry Birds is designed for touch.
