Worth it how? What have you gained?
To be fair I did it more As an experiment than everything else. The only real difference I noticed is that my internet search are more allround and it feels a bit more like the "older" internet. For example I used to open my browser just to brows around and find new stuff, It wasn't the case anymore due to the selective results of google. Having my research pondered for me is not so awesome As I expected. Going back reignite my interest for other things.
Another difference is the inability to check twitter (can't watch it if you are untrackable), and without it the world started to look a good place again.
In the cons side is the navigator.... damn that is a huge cons. Nothing comes closer to Google maps.
Was it worth it? Maybe, it has been only a month, I Plan to do it for at least 6 month and than decide. I'd suggest to setup a second phone and start from there, even a chip phone becoms ultra fast wothout the google apps ^^
I'm on mobile and is a pain to write in english cause it keeps correcting me, I'll correct the errors when I get home
