KIRF walkie-talkies / organizers that let you send text messages in addition to voice calls in the same vein as that Slide Click we saw back in the day. Trust us, typing on a small keyboard or numpad is one of the best skills they can have when they grow up -- it's a lot more practical than the Morse code we learned back in our day. The lone exception here is the feature-less RAZR knockoff that does voice-only -- hey, it's only fitting that the one phone here that doesn't knock off a smartphone have less features.
