Skype for 5 year olds?

While at a park today with my three year old daughter a five year old boy starting chatting us up like only 5 year olds can. Usualy my daughter will find away to change the topic, move to an other part of the play ground or find some other diversion to escape to rapid fire chatter of a 'strange' five year old. Today she was fasinated with what this boy was saying. He was pretending he was at home on his "Microsoft Windows PC" turning it on, launching Skype, fixing a connection issue by going to the help button in the corner, and then finaly putting on his headset and talking to his Aunt Beth whom he earlier that morning added to his contact list.  We were amazed. He asked me if I "Skyped" but then was distracted by my phone and said, "Is that a Blackberry?" I handed it to him figuring if my 10 month old hasn't yet destroyed it that it was safe in a 5 years old kid's hands.  He asked how to unlock it and then said never mind I'll figure it out. He did and quickly went to start a game of brick breaker.

I have for some reason thought the big break through age for technology adoption by kids was 8 years old.  Firefly may need to rethink their target market.....
