I think you're on the wrong site. Once salmandad (sp?) gets here, he'll write you an essay on why he loves his Android, but I think you're better off going to Android Central for that.
You can get most or all MS services there. It's not as seamless, but still works.
You can get it without Google or rip it out of the phone, and its THE phone OS for fancy things and features with themes, custom launchers, and fancy system stuff you can mess with.
