Don't forget The Matrix -- though it wasn't directly based on any of PKD's work, his influence on it is pretty clear. The Truman Show was obviously inspired by Dick's Time Ouf of Joint (though Dick's book was a lot darker than the lighthearted Jim Carrey comedy). Eternal Sunshine of the Spotless Mind is yet another PKD-lite (featuring Jim Carrey yet again). PKD's influence on Hollywood is vast.
Although his books are hard to read sometimes, the ideas expressed in them more than makes up for the fuzzy/bad form in the which they are conveyed.
It hasn't been updated in a few years, but this site used to regularly take recent news articles and link them to story elements in Dick's stories: http://fraser.typepad.com/frolix_8/philip_k_dick/
