I'm using Creative MX 200 for around 6 months. here is my opinion.

Advantage
- great style, Big LCD.
- no battery required, built in lithium battery.The battery life is very good too
- the sound quality is excellent.
- integrated FM Radio
- recording ability,FM and mic.
- menu and the control is ease to use.
Disadvantage.
- not stable before the newest firmware(1.04a). Sometimes the player will hang when you connect it to PC. and you'll have to wait until the battery run out to start it again.I'm glad Creative release a firmware to fix this major issue.those who have older firmware should update it.
- Recording quality is bad, I haven't compare it with other products.
- You'll need an usb to charge the battery, I wonder what happen if your computer is being fixed.While other products can buy a new battery.
- Required cable to connect to computer while some competitor have both internal USB connector and external cable.(eg : MSI MegaStick). this is main issue if you want to use this mp3 player as storage device.
