Previously only available in 1GB and 2GB sizes, the MG100 now comes with 4GB of flash memory. Unfortunately, the capacity increase is the only change presented by MPIO.
JPEG, BMP, and videos in the MTV file format (with conversion software included) can still be displayed on the 1.5-inch, 176×132 pixel, 262K-color LCD screen. The MG100 only supports MP3 and WMA (DRM) audio formats but is complemented by 7 equalizer presets and a 5-band graphic equalizer. A quick voice recording function is activated by voice and FM radio recording is also possible. Inside the brushed aluminium case, a 400mAh battery enables 20 hours of audio and 6 hours of video playback.
