I love my Zen Xtra 40GB - well at least I loved my Xtra. The player is great, except for one major detail - the shoddy quality of the headphone jack. IT WILL FAIL! If you get lucky it will still be under warranty. If you aren't expect to pay at least $40 for the clowns at Creative to fix it. If you think I am just flaming them, check out their forums.

Ex Output:
Negative


Ex Input:
I was amost completely happy with this soundtrack. What upsets me is that there was on particular track from the game that I loved, and it was because of this track that i payed for this c.d. It was upsetting to find that this c.d. contained every song from the game except for the one that influenced me to buy it in the first place.

Ex Output:

Positive
