Basically the Google equivalent of Pocket Reader; saves a whole bunch of links from Google News/Articles for you, Google search, and general web links. It’s not the same as your Chrome bookmarks (though at one point they were considering merging them until everyone hated it).

Beats me, I only use chrome if firefox cannot display the site correctly. And it’s a case to case basis at that, it has to be that I really really need to access that site.

Also i rarely use the Google apps that came with my phone. The most probably used one is Maps.

Edit : so yeah, I forgot. I’m on Android. There’s that, no escaping from them on my part. I can’t be bothered with using and installing my own phone OS.
