The contact only needs to be in your address book if you ask siri to call Bob, or Sally. Siri can call numbers you speak like Call 555-1212.

Can also have siri read text messages and emails to me and tell siri to answer and send whatever I say, no keyboad needed.

Work from home and also like that I can answer incoming calls with my iPhone OR ANY other Apple Devices on my iCloud account, like desktop, laptop, iPad, etc. Same with text messages as well.

Also have a Email account setup so that I can receive, answer/send emails on any of the devices and it updates the client on the other devices. Example: if I read an email on my phone, then look at the mails on my computer later, it shows the message as having been read.
Also if I start editing or creating an email message on my phone and decide I want to enter a lot more text or add an attachment and want to use my desktop (keyboad), I can just tell it to transfer the work to my desktop and it puts me editing the same message in the client on my desktop instead of phone.

Am assuming it won't be long before I can talk to Siri to do anything I need from documents, messages, and emails, up to and including TV and Lights from whatever device I happen to be close to.
