iPod shuffle 1

역사적 배경

Apple announced iPod shuffle at Macworld Expo on January 11, 2005 with the taglines "Life is random" and "Give chance a chance". iPod shuffle introduced flash memory (rather than a hard drive) to iPods for the first time. The shuffle comes in two models: 512 MB (up to 120, 4-minute songs encoded at 128 kbit/s) and 1 GB (up to 240). Unlike other iPod models, iPod shuffle cannot play Apple Lossless or AIFF encoded audio files—possibly due to the iPod shuffle's smaller processing power. The shuffle has a SigmaTel processor. One review regards it as having one of the best-sounding audio systems of all the iPod models.
