In response to the article you discussed on how Google follows and keeps a record of you everywhere you go: this is one of the reasons I just bought an Ubuntu Phone (the BQ Aquaris E5). The point +Rob Hawkins
made was spot on! When you delete your history and when you indicate that you do not want to be tracked any more, that in no way guarantees that this won't happen. I didn't want to be (what's the word you use when you know something is wrong but you couldn't be bothered to do something about it) any more about my phone spying on every move I make.
I'm slowly but surely moving away from all Google's services that mine as much data on me as possible and then sell it to the highest bidder. That's why I moved away from Gmail to Fastmail, I changed my search engine from Google to DuckDuckGo, I switched from Chromium to Firefox, and that's why I'm shutting down my Android phone and bought an Ubuntu phone.
All the data I want to be public, they can analyse as much as they like, like whatever I share on Google+ or the video's I put out on YouTube, but I want to be able to control what I (want to have) share(d) with others, not to have web front end that says: "We won't track you any more, really we won't, cross our hearts."
