Legg's formal definition of intelligence models an agent exchanging symbols with an environment, both Turing machines. Like all models, it isn't going to exactly coincide with what you think intelligence ought to mean, whether that's school grades or a score on a particular IQ test.
You can choose to model I/O peripherals as either part of the agent or part of the environment. Likewise for an input delay line. In one case it lowers intelligence and in the other case it doesn't. We can't measure expected reward over a Solomonoff distribution of environments because that requires infinite computation. But we can approximate reward as dollars per hour over a set of real environments of practical value. In that case, it does matter how well you can see, hear, walk, and lift heavy objects. Whether you think that's fair or not, it matters for AGI too, whether it's purpose is to automate human labor or to upload your mind into a robot.
