Once the Apple iPod Classic 1st Generation was introduced, music storage and portability were changed forever. This classic device can store up to 5 GB worth of MP3 files, meaning it has a maximum storage capacity of about 1,000 songs. The 2-inch monochrome LCD display screen is easy to read and shows both the song title and artist of the song currently playing. Users are able to quickly and easily navigate through their playlists, songs, and artists using the iPod’s scroll wheel, center button, and auxiliary button. Add in an impressive 10-hour battery life and iTunes compatibility, and it is no wonder why iPod is the most popular music player on the market.
