Review on Mattel I4009 Radica Girl Friendchips by Aaron Jimison

I don't have a friend's chipset, but I like it. But I want to know if it is worth $20? Well, firstly, if the teacher isn't blind, he can easily see you typing something with a friend's chip machine while with pencil and paper he thinks you're doing the task. And how do you get the chip to your friend so you can throw it across the room? Second, I'll get a cell phone with SMS in a few years, so is it worth spending that kind of money for a few years? And what if I want to send a note to a friend who doesn't have another friend's chip? And last but not least, if the teacher sees it, they will definitely confiscate that (I spelled that completely wrong), and then the school will turn it into a rule that no one can have it!* Is it worth it?*
