ubuntu hardware testing tool to count ubuntu user-base

During first time installation of ubuntu, the hardware testing tool will test your hardware and with your approval it will get information about your hardware such as: (IP address, processor name model and serial, network card MAC address, RAM, regional language, your country, Optical Drive e.g. CD/DVD-ROM, Display Adapter, SCSI Adapter and IDE Adapter) and it will send them to canonical so they can count the number of users using ubuntu.

when you upgrade to a new version of ubuntu then you will not be counted as a new ubuntu user, but they will be sent to canonical to ensure you are running the latest version.
During installation, if internet connection is not active then the info will be sent when you start your computer for the first time and when you setup your internet connection(with your approval of course)
