Google Account or Gmail to Setup Android?

[johnnycakes2]

In anticipation of getting an Android device, I am still confused whether a Google Account is required or a Gmail account. These are two separate things. I currently have a Google Account and use many Google services under a myname@yahoo.com username. I use Bookmarks, Finance, iGoogle et al. and they work great. I was under the impression that upon initial setup of Android you could log-in a Google Account and it would "fetch" your online data. Now I'm beginning to think you must have a Gmail account (which I have, but prefer not to use). Can anybody clear this up?

BTW, I've read the user guides to the Nexus One and Droid and neither clears up the issue.
