The media player does MPEG-4, digital audio, and pictures. But it also has a WiFi connection and a QWERTY keyboard, for chatting on Google Talk and Yahoo Messenger (No AIM support, sorry.) Wait, wait, wait! It also works as a wireless Skype phone! And it has an Opera browser. And it can wirelessly stream music to other mylo owners in the area, ala iTunes. The mylo has 1GB of flash memory, backed by a Memory Stick Pro Duo slot. Its screen is a 320 by 240 pixel 2.4-inch LCD.
