I would be more concerned about the microphone. I can easily cover the camera with tape. Also, random pictures of me programming or reading HN are probably less damaging audio recordings of conversations I might be having.
My current Thinkpad has a physical switch to disable radios. I'd like to have a physical 'privacy' switch that cut the power to internal microphones and cameras. To be security aware, this has to be an auditable hardware power switch, and not just an interrupt/driver/bios combination that could be bypassed. It's also prefereable for security to have a an off-by-default switch, than an activity light you might not not…
That's unfortunately the exception rather than the norm. I have seen laptops with switches for WiFi, and camera obturators, but manufacturers hardly think about these things. It's obviously not an Apple problem only, but it certainly hinders usability to have physical switches. Yet, I really wished they'd make that standard for all media peripheral (and not just on PC, but any device coming with these features). That would however be easily considered as an admission of failure to provide a secure software environment to their customers, and they might not like that aspect of it.
