Yepperz, times sure have changed. I remember growing up & watching black & white TV specials on how one day, we would be able to use a telephone with a little screen next to it to talk to our friends and see their faces. And how one day we'd all have 2 way wrist TV radios like Dick Tracy.
BTW, Japan did come up with a device like that about 2 years ago, but deemed it too heavy for use. I think it was like 10 oz or something.
Good thread, the stuff up there is true nowadays.
