Whatever happened to the minibar?

I quickly read this article from the Washington Post, about the death of the hotel minibar. I can easily understand why: it was costly and now it is pretty much obsolete. All the same, I can't help but feel a bit sad about this. I know, I'm terribly nostalgic and this is pushing it, even for me. I rarely if ever used the hotel minibar, nevertheless I found their presence reassuring: you knew there was a safe supply of food and drinks. I am happy to learn that some hotels are trying to reinvent it and to make it survive.
