Apple Almost everything has a processor and/or memory chips these days, including keyboards. Apple's keyboards are no exception; they have 8Kb of flash memory, and 256 bytes of RAM. K. Chen has found a way to very easily install keyloggers and other possibly malicious code right inside these Apple keyboards (more here). Proof of concept code is here as well.

This certainly doesn't seem as bad as the sensationalists would like you to believe. The Apple firmware updater has to be run, a break point is set and from there your keyboard can be compromised. First off, how is a remote web site going to run this Apple firmware updater? What modern browser can arbitrarily run executables on the host machine (well, perhaps, aside from IE6 but that's hardly modern). Second, I've used the Apple firmware updater. Before it does anything, it prompts you to update the keyboard firmware. This is not something that will happen out of the blue, you must explicitly run the firmware updater first and accept the upgrade and, on OS X anyway, you then need to enter your administrator's password to confirm the action.
So what we basically have here is a vulnerability that requires physical access to the machine in order to be enabled, and further relies on the keyboard not being at the latest firmware version, as the firmware updater won't download or run an image unless it's newer than the current one installed. The only way I can see this being a serious problem is if a hacked firmware image were somehow placed on Apple's servers (rather unlikely), or dns poisoning to redirect the firmware updater to a different server (possible, but for a rather small payoff by modern standards of cracking). It's a threat, certainly, but not a huge one.
