Re: What's the point of DRM?
iOS means iPad too, and they let you download HD video. It's not just crappy 320x240 res stuff. They want stuff you download to only last X days, and only Y days once you start playing it; the functionality is to let you download to view without WiFi access, not to let you build an offline library.
I don't know why that's the functionality but they own the content so it's kind of their choice (no you don't own it just because you pay TV license).
