Even as a tech savvy person I'll admit it's a bit of a problem to "take your toys and go home". Google purposefully made themselves an integral part of most of our lives so it really is about as involved as moving homes when it comes to migrating away from Google.

I would just say that moving one service is better than moving none of them. It's a slow process but it is doable. I'd say email is easiest to start with. I haven't converted any accounts yet (i.e. using my new email as the username) but for any new accounts I've been using my new email and occasionally closing accounts associated to Gmail. There's probably a ton of services you've signed up for but never use so closing is way easier than migrating.
