Beeping or clicking keypads on PDAs or phones is indeed annoying.

But nothing is more annoying than "push-to-talk" on those **** Nextel phones here in the US.

On a domestic flight, as soon as you pull up to the gate, seems like there are always 2 or 3 of these people whipping out their walkie-talkies and talking on loud annoying beeping speakerphones.

I'll be glad when this fad passes. It will pass, won't it ...
