Couldn't help but notice: $398.70 per hour = $9568.80 per day = ~$3.5m per annum. They obviously get a discount...but still. What kind of discount do guys like this get?
For what it's worth, 3.5m/yr is about 0.08% their revenue.
Microsoft do this all the time - its great publicity. It would be interesting to see if they (Microsoft) have something showing similar results...
