I liked the MPIO player. It had a small compact size, expandability to hold more MP3's in the future, supported both WMA and MP3 files, and overall was a nicely packaged product. I was not a fan of the low battery life, of around 10-11 hours, but its a limitation of the majority of MP3 players. A bass-boost function, apart from the EQ, would have been a nice feature to have, although with enough modification of the user-preset eq, I was able to get the bass to a decent level for the music I listen to. Compared to my friends Creative Muvo, the MPIO made quite a better impression on me.
