I love technology but cell phones are hell-spawn. There's nothing worse these days than someone lost in their own world in a queue somewhere, thumbs furiously pumping away like the message they're sending must somehow be sent in the next 5 seconds because their head is about to explode and the information they carry is the key to saving humanity.
You all know who you are...
Now that I think about it, it's all summed up for me in Ghostbusters when Egon attempts to break out the calculator in the library at the beginning of the movie and Venkman knocks it out of his hands and says "STOP THAT!". Every time some homer tries to use their phone to Google something asinine that came up in conversation because they don't believe you, that scene runs through my head.
