Matt Lakeman's "Notes on $PLACE" have become my favorite random email update to get. They're all excellent. If anyone knows more about him (does he write anywhere else?), would love to learn more about his background and travel experiences.
I think that's fair for trying to master physics or to become a physicist. But if you're looking for an intuitive understanding of the concepts or relearning it, which seems to be what the OP is looking for, Feynman-style seems like the optimal type of book.
I don't think Feynman's books are a replacement for a more traditional physics textbook as a student looking to pass a class, become a physicist, or a hobbyist trying to master it, but I do think they're pretty ideal for someone who wants to get much stronger grasp of the concepts than a layman without having to go through the struggle associated with solving problems they'll never actually apply.

* That said, I'm generally sympathetic to caveat emptor, as well as the idea that the provider of the OS should be spending gobs of resources on proactive protection against apps they don't even know are malicious yet. I also don't see why there can't just be a secondary app store where apps don't get the same level of scrutiny and that fact is made very, very explicit. Call it Caveat Appstore
