There should be a certain amount of trust involved. A vendor _SHOULD_ either 
destroy the platters or bulk erase them. I would doubt that a vendor would 
take the time to extract the data as data recovery is labor intensive.

This is very true. The level of encryption depends on the value of the data 
to you or someone else. 
If I were a company executive carrying a laptop, I would certainly make sure 
the data including email was encrypted. But, the bottom line is the value 
of the data. I don't encrypt anything on my laptop because the only things 
I keep on it is stuff for my teaching.
