Why doesn't anyone make an e-cig battery that doubles as an input pen for a touch screen? I use my 510 on my tablet PC but it isn't accurate due to the flat LED tip. It would merely have to have a pointed end to double up as an input pen, and as it is always in my hand it seems the perfect solution for gadget users. It could still have an LED in there, maybe one that activates on touch 
I'd buy that for a dollar.
