Re: Uh... what?
Yes, and all the functions on the phone work just fine. I can use the built in apps, I can use the Internet, and even the Email app. It's definitely works just fine.
You of course get more, if you do want the Google stuff, but it's perfectly optional. Android has no lock in at all. You aren't forced to use Google services, and you aren't forced to use Google hardware, you can pick from basically any other hardware manufacturer except Apple, all your stuff will continue to work just fine (most phones come with migration tools that don't assume Google services).
