Disabling access to portable media/memory devices is trivial. Furthermore, the requirements of HIPAA (only one P) and SOX tend to be a little vague on the specifics. They talk a lot about best practices without saying what those practices are. As far as iPads/tablets, third-party computers, and so on, there are a number of security tools available that allow you to securely deliver applications to those devices while still preventing data leakage (usually through Citrix/RDP, VDI, or similar techniques).
