Terminal U:

Overpackers take note: this could be the invention that changes your life forever. Or it could also be the most gimmicky travel accessory you’ve ever seen.The “Hop” as it’s been called, is a suitcase that you don’t have to lug through the airport. You don’t even need to pick it up, as it follows you wherever you go – a bit like a lost puppy.

This is one of those things that, when you read about it you think, “Hey – that could be kinda cool!” Then you watch the video and think a bit more about it you realize, “oh yeah…this is a really stupid idea.”
