I try to maximize my “hostage” time as much as possible- waiting in line means it’s checking email time and while taking showers or exercising, fill that time with audio. Here’s a fun way to listen to podcasts (audio programs) in the shower. Project at a glance: Creative Muvo MP3 player -> Stereo wire -> RF transmitter -> RF input of 87.7FM -> Sony shower radio. I’m not sure why we haven’t seen a waterproof wireless MP3 player/receiver for the shower to stream in your music yet.
