From my experiences, there are several signs your infatuation with technology has taken a more serious turn...
This is you first thing in the morning, and last thing at night:
You can't go to bed without your phone. And the first thing you do when you wake up is reach around blindly for your phone.
A mobile device is more than a handy tool for making calls or browsing the web; it's a soulmate, your link to the rest of the world, your main source of information.
It's as vital to you as a light-sabre to a Jedi.
You feel anxious and sick when your laptop can't find any Wi-Fi signals in the vicinity.
"Searching, searching, searching... Why is it not connecting!!!"
Anyone who knows that feeling of frantically trying to guess passwords of protected Wifi accounts knows what I'm talking about!
People like this end up missing out on things like camping or safari holidays, simply because they can't serve that connecting between themselves and the warmth and security of being online 24/7.
You start using complex technology to manage and operate things that could easily be done through other means.
For example, trying to book out a meeting room in our office required registering to a service and updating a calendar that would then alert everyone else in the office that the meeting room was unavailabe.
