It’s often easier to make a complex system from ready parts. Instead of providing specific functionality, the resulting
device does a lot more than you actually need. In so far as the system manages to do what is needed, nobody should complain about the extra functionality. However the extra functionality usually has severe consequences for the device’s level of security. An interesting example of this was presented at Hack in the Box this year.
A wireless presenter – designed to allow only a couple of functions (next/previous), easily achieved with a mouse and a keyboard – can allow someone to take over your computer while you make a presentation.
