Just out of curiosity, I wonder what the savings would amount to if this company used something like SpinRite to fix / recover failed drives? Although I've never used it from what I hear its pretty good at saving drives...
It's actually not that good at saving drives, however it sometimes saves your data. Lately I've used it to recover a 250 GB drive that was part of a failed RAID-5 array, and miraculously got the data back.
So SpinRite may be handy, but throw the drive away after use.
If GMail were built with Drupal, nobody would have ever heard of it, because it would suck and would have never gotten the kind of traction that GMail actually did.

Should give you some idea about the quality.
