My company has pretty strong rules on laptops and data security. All laptops are encrypted, and a group policy prevents removal of the encryption. All laptops require a power on password, and there are occasional inspections. Storing data on a laptop is discouraged. Losing a laptop results in an unpleasant conversation with a senior manager about the circumstances of a loss - and a requirement to fill out some forms and attend a data security class. We lose very few laptops, and the majority are lost via theft.
