I don't see ditching all your Apple devices as a requirement, my buddy is a huge Google head but uses all Apple products.

I'm deep in the Apple eco-sytem, iPhone, MacBook Pro (work), Mac Pro (Home), iPod, and a mostly unused iPad. My relationship would be listed as complicated though. I'm not a huge fan of Google but I can't give up on Gmail, GChat, Google search and maps.

On my iPhone I use the Gmail app which is fantastic and I'd argue as good as mail. MacBook/Mac Pro Gmail + a notifier, Adium (IM client).

If you have a real beef with the OS, you can always install Ubuntu on a partition and give it whirl. There's no need jump ship in one swoop. Figure out what works best and run with it.
