What is a TeamViewer Account?

Why would I want to Assign a Clients PC Teamviewer ID to my Account?

This is used by going to: Extras >Options > General > Account Assignment. then Assign to account.

It says "By assigning this device to TeamViewer account, the device can be reportely managed and monitored by the acount at any time"

If i program the Clients Teamviewer ID an Password to a Group on my list I can access it remotely. I dont need to see if the clients Firewall is dissabled or not or if the hard drive is full or not.

Then Why? Can someone explain the extras benefits?
