You know that feeling when you encounter a new word... and then within a couple of days you start noting it everywhere?
Well, if you hadn't spotted it already, let me open your eyes to this particular neologism:
Normob = Normal Mobile User.
Basically a non-geek, non-mobile industry person who wants to use their handset to make calls, send SMS's, take some photos and maybe play a built-in game. Maybe they use the MP3 function, and occasionally they'll Google on the phone to cheat in a pub quiz. But someone who doesn't know what a smartphone is, and doesn't care. Not interested in "finding" things, downloading applications, using GPS, changing the softkeys, customising the menus or anything else. Someone probably on prepay, and who chose the phone either because it looks nice, or it's an update of their old one.
About 90% of people, in other words.
I'm not sure who coined it, but it could be from here or here.
