Leave it to two design driven companies like Apple and Burton to team up and make an integrated weatherproof snowboarding/ski jacket. It's a bit pricey, but made with top of the line Gortex waterproof fabric and has controls for your iPod integrated into the jacket arm exterior. Controls are provided by SOFTswitch and utilizes an interactive textile data strip.
