Best thought-capture tool when your hands are full?
I live in NYC without a car. I buy groceries weekly and walk home with my hands full (about 13 minutes walking time). Sometimes on the way home, I'm hit with good ideas, but it's a real pain to set down the bags and dig out my pen and paper to capture my thoughts.
I was thinking about maybe using one of those pen-recorders. I could probably maneuver a couple of free fingers (while carrying bags) to click the record button on one of those pens and record my thoughts via voice into the recorder.
I was just wondering if anyone had any better thoughts on the matter?
