Got elementary kids?  I do, and no, he doesn't have a cell phone.  Won't for a long time.  We have a Wii, though. One admittedly mundane but cool feature is the ability to send and receive e-mail with it.  My son is never out of the living room for long when he's home.  If I am away and want to just drop him a line, he notices the blue Wii e-mail flash pretty readily, and knows how to reply.

Doesn't happen often but it is nice when I need it.
