So you have gone to the trouble of purchasing a 2G Shuffle (the real one, made out of metal) as a "second iPod"; you have at least one laptop upon which you depend for many of the essential features of 21st century life; then why in heaven's name would you want to be stuck with the brain-damaged dock that Apple insists on selling with the Shuffle?
The IncipioBud plugs into a USB port and into your 2G Shuffle, and you are off to the races. Small, easy to fit in the tighest carrying spaces (mine stays in the carry case of my ASUS EEE PC, which is itself breathtakingly small and functional), and just plain cool.
Works with Mac, Microsoft and my ASUS Linux-derived OS -- so buy one! You'll thank me later.
