The iriver E100 is iriver's first North American release since the popular Clix2. It is not considered a top-of-the-line mp3 player, but sits more in the lower end line for its class. It is a flash-based player and comes in 2GB, 4GB and 8GB models. True to iriver's previous media player models, it supports a wide range of audio formats and video formats, although video will require some conversion to work. The E100 has some nice added value for a player in this price range such as: built-in speaker, FM tuner, voice recorder, microSD slot and text reader. Requires Windows XP or or Windows Vista (no Mac support).
