This whole thing makes me very suspicious of Apple's and Microsoft's whole disk encryption technologies. I can't help but wonder if back doors have been inserted into the products.
If you want your data to be reasonably secure against someone who casually steals it then they're fine but if you want to be secure against government employees, or even well connected corporations, then Apple & Microsoft solutions are not very useful.
