Electronic device: never.
Gloves: always.
Whenever I'm travelling and I want to put my device down (be it phone, tablet, mp3 player, ereader, pda, you name it...), I always put it in my bag. But every year I had to buy two or three pairs of new gloves because I had lost one glove somewhere (always one...) Now that I no longer take any public transport, I don't lose gloves anymore
