1. FB - I would be better off because I wouldn't feel compelled to see the ridiculous crap my mother and other family members are posting. I wouldn't have to sit through BS discussions at work (from people that don't know dick about society or media) about how to leverage social media to increase traction and profitability or how to leverage it as a prospecting tool. -Ugh. 2. Google: This would suck only from a search engine standpoint. They're the best at it. I could take or leave nearly any other platform they have. 3. Apple: I would miss my iPhone. I use it a lot and I strongly believe it's the best "smartphone" out there. I would miss my MacBook Air but I'll be honest here, I could use a PC and still be alright. MP3 player is my phone these days. Don't use apple for anything else. 4. Rarely use Amazon, wouldn't miss it at all. Now my wife on the other hand, she's all over Amazon. Overall, I don't think much would change in my life. I think I would just find replacement services/products. A more interesting question (IMO) would be: Thought experiment: Social media, smartphones and online retailers disappear overnight. Are you better or worse off? -That I'd have to give more thought to.
Google and Apple I would miss for searches and iPod, respectively, but I would manage easily. FB sucks donkey scrotum and I don't use it, so its already dead to me.
