AppleTV

If I understand this right, AppleTV now streams/redownloads video as well as audio previously purchased from iTunes.  Which means that (setting bandwidth issues aside), when traveling, I can just bring my AppleTV and plug it into a hotel TV and have my entire (to the extent iTunes purchased) video library available.  I currently use the iPad as a video library but even with 64g, the library is limited.  Too bad hotel bandwidth makes this more hypothetical than useful for now.
