Word on the street is they offered it because their DCs are so overprovisioned on storage that it doesn't really matter. Time will reveal whether or not this is true.

As a sidenote, I'm disappointed by how slowly HDD capacity has been increasing the last few years.

100MB -> 1GB: 10x Was amazing

5GB -> 20GB: 4x Amazing

40GB -> 250GB: Hell yeah!

...

Nowadays the rate of increase is way down. 10TB -> 20TB: 0.5x meh. In the next 5 years we _might_ get a 30TB drive? Yawn.
