Google is to me what Facebook was a few years ago. I do have a Facebook account but don't want to use anything Google. Yet they have a sneaky way of trying to force you (and others) into it. I think it's scary just how well Google has done at shoehorning themselves into the education market. I frequently encounter kids that think google is the internet. They think all email is Gmail. They don't know other search engines exist. They only know YouTube, mostly because of Google's placement. They don't know there are other forms of Maps. (again, Google's placement of their own products.)
It's scary. Facebook hasn't gotten to that point. They've tried with mobile devices, and they were a flop. We don't see Facebook Maps yet or a lot of Facebook Videos or whatever being shared around.
