Oddly, i feel must less strongly about Amazon's hold over the the platform the Kindle represents than i do about Apple and its hold over the music platform iTunes represents. Irrational? Probably. Uneconomnical? maybe (i buy far fewer books than i do albums/audiobooks). I can't fathom why but i just somehow feel like, when i've read a book, the ideas it containws stay with me and become mine whereas an album is something that perpetually stays somehow external (apologies for the airy-fairieness of that: i'm not sure how to express it but i feels like a difference thats significant for me and i'm curious whether anyone else feels the same).
