Well, my 14 yo got a Sony PSP with his Christmas money, and seeing as it has a 802.11 wireless connection, and a browser, it wasn't long before he was asking me for the key to get on my router. I investigated the Parental Controls available, and to my dismay it seems there are none other than browser/no browser. Not much of a control in my opinion. I posted a thread on Sony's official site, and it looks like its definitely stirred up the younger posters who think they should have unfettered access to the net.
To me this is a real issue. I have 6 kids in the house, and 4 are teenagers. My rule is, if you want on the net, there is a linux machine with filtering installed and maintained by me that you can use. There will be no internet in your rooms or behind a closed door. This applies even to the 17yo who just got a laptop for Christmas and will be shipping out to the Navy in a few months after turning 18 and graduating high school.
The bottom line is kids of any age can pick up a PSP, jog down to the local Starbucks or McDonalds, whoever is hosting a free Access Point, and browse the net without any supervision. There's dozens of replies telling me to just trust my kid, but it goes much farther than that in my opinion. Sony has placed a tool in the hands of minors that allows them to access Porn, or anything else adult oriented floating out on the net. Isn't that basically illegal? Sony really dropped the ball on this one.
They also did a poor implementation of Parental Control. They have a 4 digit code you can set up the controls with, and all you have to do to subvert this is pull out your media card, and do a hard reset on the PSP, and you are back to square one, completely unlocked.
How long will it be before some kid is arrested viewing porn in a McDonalds in plain site of customers? Unfortunately, I think that's what it's going to take to make people aware. Don't get me wrong, I love the technology, I just wish Sony would have given us parents who actually care a little more control.
