> One thing that your completely missing, however, is that people leave their phones on most of the time. Encrypted drives only work effectively if your system is turned off at the time it was stolen.
Alternate perspective is that encryption and never-turned-off make a good combination as then if your phone is stolen/lost all you need to do is remote-shut-down. If you still have the phone, this is just an inconvenience. If someone else has it, they lose any access to your data.
All the value of remote-wipe and almost none of the cost.
