I agree with Jacob's list over the official list. I was going to suggest several items he listed, including vaccination and the transistor.
But in terms of impact on daily life, the car - or Model T if you prefer to be specific - has, I beleive, the number one impact on life, followed by the TV (regretably?) that consumes so many hours per week of the average person and is his conduit for news, entertainment, and all too often cultural values.
The airplane also has had a major impact and I would replace the Apollo 10 capsule with, arguably, its predicessor.
Birth control pills, and other methods of contraception, have also had major impact, not only in terms of the sexual activities of those practicing it, but all the lives not on the Earth now because of it.
