So - I am not what you would classify as an "Early-Adapter" when it comes to this digital stuff - but I have to give a shout-out for SKYPE!
I can sit in Ohio and see & talk to my kids in California, Florida and Chicago and my wife down in the Carolina's. It amazing how much better it is speaking and seeing. Kind of like radio and television when TV came onto the scene. (although I don't remember that, before my time)
Picture in picture in picture ..... Skype'n with my son!
