yep. i mention this a lot, but it's scary how well Google has done in the education market these days. Kids (at least all of the 0-6th graders I know) equate all things Google with "the internet." They know nothing that isn't Gmail. To them, "Gmail" IS email. They know no video sites besides YouTube. They go for Google Maps. Even on mobile devices where Google is the default search engine, it still feeds you Google services before anything else. Notice how on the iPhone, you can't copy & paste an address from a web search into Maps? Nope. It opens web version of Google Maps and prompts you to download the app.
The average user is going to say, and often times because they have no idea how to leave. Google is keeping them there.
