This is an excellent point. Last week I was at the mall where I saw a new Samsung TV that had a kinect like camera thingy built in. It claimed that you could use it to play Angry birds and navigate the TV using only your palm/hands. Guess what? Thanks to being horrendously inaccurate and jumpy I got gorilla arm within just a few minute of demo usage and said "fuck it, I'm not interested anymore. Samsung should really fix their image processing quality". My second experience is with the Asus eeePad Transformer. It's great to randomly touch the screen when using a mouse would take a few seconds extra but in the long run you'd end up using the keyboard/mouse subconsciously since your arm starts hurting.
