Physical wear most likely, mice and keyboards get hammered pretty regularly and over the months/years it takes its toll. Especially travel mice, which are usually cheap and opt for light-weight builds over solid construction in my experience.
"As a result of all this hardship, dirt, thirst, and wombats, you would expect Australians to be a sour lot. Instead, they are genial, jolly, cheerful, and always willing to share a kind word with a stranger, unless they are an American." -- Douglas Adams
