Which electronic gadget you had come across your life and said wow what a invent

my computer, my playstation 2 concole and my cell phone they are all 3 great inventions.

i think that the cellphone is one of the greatest electronic gadget that popped up in my life. it is a real good and helpful gadget because we can send text messages, call one another and simply just be able to connect with other people wirelessly, wherever we are at anytime we want.

I have to say that ther are a lot of fad inventions and those that have lasted the ages with a few upgrades along the way, such as mobiles, tv, radio ect, but the inventions that make me go wow are the ones that save lives like ones that work as the kidney does, drain fluuid from the brain, breath for the body when it cannot for itself and generally save and improve lives.
