If only they made it for the Mac since that's what my kids use. Although my 3 year old already knows how to type pbskids.org and get to the games he wants. I think what would be better is a usb key that brings up a child safe browser with easily clickable links to all the children's sites. now that I would buy!

this is a great innovation =P now why didn't i think of this before them? haha

http://www.PeanutButterSoftware.com does this now and for less money. It locks everything down without even having to exit the current user account. It blocks obvious things like Ctrl-Alt-Del and the Windows key to more obscure things like the CD-ROM autorun and Windows popup balloon messages that just beg kids to click them.
