Well I'm a Mac user so that boat sailed long ago. I've been trying to google the problems with iTunes and not turning up anything, presumably like Amazon and Kindle, iTunes can remove material from your hard drive. But Amazon is really no better in this respect and it's rep for censoring GBLT material (and it's lack of support for authors whose publishers are issuing ebook versions of their works without owning the rights) and so forth doesn't make me see any reason to prefer it to Apple in terms of who gets my cash.

I gather the DVD of s5 will be available from 2|Entertain within a week or so of the last episode airing.
