Dual-touch mousepads would be much better, in my opinion. They're not screens, so smears aren't as noticeable.

Just remember to wash your hands so you don't end up getting sick. (Always true, but thought I'd mention it anyway)

I'm making my appointment now for surgery and throwing out my mouse and keyboard.
Back to reality, I bet it will be pretty cool but the greasy screen is something I wonder about. I admit my fingers are rarely in a bag of chips all the time but keeping the screen clean would bother me.

Presumably we use the Standard International Two-finger gesture?

.... they saw it in a film a thought it might be pretty cool to implement it on a shiny plastic thing.

Step away from the 'smear grease and grit all over my soft plastic screen' ideas.

And, judging by the images in the link... you can only use this emerging technology if you happen to be Lobster-boy.
Though if [cr]Apple released the iClaw for people who wanted body-augmentation to use it, they'd fly off the shelves too.

Shonky.

It's hard enough to keep people from putting their greasy mitts all over my screen when they want to point out a word in a paragraph or some stupid image. Why would people even want to touch their screens? People are lazy; they don't want to lift their arm to poke at some screen on their desktop. Then again, those Mac users are strange.
