What is your favourite iconic-but-ultimately-useless gadget?
Mine would be the Sony Rolly.
I'd say it's iconic because of it's iconic design. I mean, it's the shape of an egg! It's one of the gadgets out there that is very unique and intelligent, in this case is due to its ability to 'dance' along with music. However, I see no practical day-to-day use for this, well except as a conversation-starter.
What devices do you know/own that are iconic and unique in their own way but are ultimately not useful for day-to-day use?
