I bought an Ember mug because I thought it was silly. I ended up really liking the temperature control. I don't rush my coffee/tea. Now every sip is as hot as the first one.
The new Ember costs, I think, half again as much as the first iteration. It's a cute gimmick but I certainly wouldn't pay what they're charging now.
History seems to agree. Seventy-five percent of films from the silent era have been lost forever. Television shares a similar fate.
When a new medium is created, it seems we don't put much thought into preservation.
