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?
That is pure Ignorance to what the user wants. And we dicussed that on this site already. It seems to be fairly obvious to most that there is a big difference between having more than the half unusable and having a tiny bit used.
Defending Microsoft in that brainwashed-looking way serves neither you nor them.
