Here are some of the options for advanced setup (and there are lots):
Receive voicemail notifications via email, text, or both, or none.
Forward calls to another phone, to all phones or to Google chat.
Text forwarding option to an email address.
Change recorded name.
Change recorded message.
Call Screening to force unknown callers to say their name.
Do Not Disturb.
Call receipt scheduling.
One of the coolest things is to create Groups that allows custom greetings and custom screening options.
Also, if you have a website or webstore, you can create a "Call Me" widget.

I'm going to stick with it for a while and see how it all shakes out.

Oh! And your call history, messages, etc. are all stored in your Google Voice box, just like a gmail box. Of course this means they will mine the snot out of your data, but if you are OK with that, then it is kinda cool.
