Haha! Great idea!
And as to Smart Phones... same here.... I actually got one as a present... but I still use my normal cell phone.... I do not like the greasy look and feel on the glass of the smart phone whenever I have actually USED the phone, as in holding it to my ear and making a phone call.. duh... I just do not want to bother with all kinds of apps that want to have all my information (and send it where? And to whom? And for what purpose? And access the internet without my even knowing? Racking up huge bills if I happen to go abroad UNLESS I remember to turn that all off whenever I happen to go abroad) ... etc etc.. and I most definitely do not wish to go through life with my field of vision reduced to the screen of a phone... like so many people do whom I see every day... naawwwww
Neat idea to attach a PV to such a phone though
For those who like that stuff.
Maybe the PG even prevents bacteria in that smeary film on the glass after a person who wears any facial cream makes a phone call
