Doesn't matter how much better the specs on this device are. I'm uncomfortable using it to purchase content that can be revoked without warning or appeal[1] and nothing short of a popular article on Hacker News can reverse their decision (and only then as a PR issue).

I realize you're also "renting" content from Apple but the company doesn't have a history of abusing this and Amazon does.
