My hubby works in IT so he installed a web program on his daughter’s computer so that he can logon to it even though she is in another state. He can see what sites she has been to and read any instant messages. He also likes to mess around with her and start typing or doing things while she is on, she thinks it’s cool. She has given him all her passwords and she has always been honest with what she is doing. My daughter is 5 so I keep an eye on her when she is playing games on my computer.
As for cell phones, I think some kids need them (no matter the age) to get a hold of their parents. I don't think kids need all the fancy stuff that the phones have now.
