Input:
I bought a Jukebox in September and spent some time loading all my music on it.  The first time I tried to use in without AC power the batteries lasted about 15 seconds.  Creative said it was a battery problem and sent me new batteries, but that did not solve the problem.  When I asked for more help, they informed me that the product only had a 90 day warranty and that there was nothing they could do for me.
Unbelievably bad customer support.  I will by nothing from Creative Labs ever again!
