Just wondering as I have just bought a Creative Jukebox Zen for my son and the battery is not replaceable. Given that the warranty is just one year on this product it seems that it will last as long as the battery. On the new NX model the battery can be replaced when it finally dies. My fault really, should have done a bit more research. Considering that the thing costs over £200, it becomes a very expensive item. SO BEWARE.
