Truth is, a LOT is from Apple. Don't forget that Apple has been around for a long time, and without them a lot of the things we take for granted in tech land wouldn't exist. They patented a lot of those things too. Common sense helps too. Pretty easy to see the line of demarcation pre-and-post-iPhone. And the iPhone was based on the original Newton, and a lot of underlying technology has it's roots from pre-OSX Apple.
