Oh, for security reasons! Whose security? Let's be honest here: the content owners. It's classic DRM: you buy the device and it works for someone else. My solution is to strive to avoid buying, supporting or discussing DRM-crippled devices except to reveal their true nature to the wider community. "Don't be evil!". Puh-lease. Anyone know what Google spends on PR? I'm sure it's either hidden or shocking.
