They give you hardware that is capable of storing the advertised amount of data - they advertise it the same as any other vendor (nobody advertises "usable diskspace" unless there is a 59GB iPad out there).
When do you think hardware vendors should start specifying available disk space as part of their SKU? When it's less than 10%? 20%? Should this value include pre-installed applications?
