I think sometimes we muddy the waters mixing issues together. Is the real question, mobile devices, cloud storage, and other consumer focused technologies? We all have to struggle with these issues. I don't think BYOD makes it any better or worse. My company enjoys the benefits of BYOD, but still has to focus on issues like keeping corporate data out of personal Dropbox-like services, mobile security, etc. The issue of who owns the device is increasingly irrelevant. Management tools are readily available and mature enough to manage the devices. BYOD can actually help focus on the core issues instead of pretending that your users aren't working around your controls and using personal e-mail accounts, cloud services, etc. just because you don't have a BYOD program.
