Era of telecommunication

Is it that easy to communicate? Say, you got the latest-state-of-the-art gadget i.e. cellular phone, iPod, PDA, internet messenger, even telepathy, or whatever say you. Will that be easy to communicate?

No, of course not. RIGHT, in order to do a communication process, not only YOU got the device, your counterpart also is required to have one (may that be same model, same system, or same protocol).

Granted, you both got ones. Now communication is underway. Hmmm... I still got something in mind that is nagging and I am sure that thing will hinder the process of communication to go on. One CAN make a connection. He/she can do it instantly once he/she has got the device that is required, rite?

WRONG! A got cellphone, B got the same, even with the same model. When A tries to contact B with his cellphone it now depends on B to decide a faith of the intended communication to happen, will B pick it up? will B ignore it? or will B be available at the time A is calling?

Gadget, ability, intention, timing.
I am deprived of one of those, at least once in several attempts.
