An article from the NYT that first made me roll my eyes, but had a interesting game:
http://www.smh.com.au/business/innovation/techs-frightful-fi…
"If an evil, tech-phobic monarch forced you to abandon each of the Frightful Five, in which order would you do so, and how much would your life deteriorate as a result?"
I'm not as convenience dependent as the author, and I could ditch Amazon and Facebook without blinking. I'm typing on a Macbook, but it is the first time I ever used a Mac as my primary computer, so Apple could go too.
Microsoft used to be critical to me, and I still use Word a lot, but I could switch to Linux and Open Office without too much pain.
But Google, wow. They are really embedded in my life, with Gmail, search and Android being used many times a day, and maps, photos, and a few other services are the ones I use for those specific tasks. Very hard to give up, and I was online for a good few years before Google existed, so I remember what it was like in that dark time ;-)
Don't forget one of the most embedded pieces of technology - pacemakers.
