Query: Very bad experience.

I was very excited when I bought the Zen Sleek Photo; the screen is bright, the music sounds excellent. Unfortunately, navigation is horrible. The touch pad design causes constant false selections, sometimes interrupting (and basically deleting from the playlist) the music you are already playing. I can't imagine a test panel NOT complaining about this abysmal design. I guess Creative just did not listen. Then, to boot, the unit crashed after 10 days of owning it. My computer no longer recognizes it, and the screen is black. I am currently in the process of returning it. Please, save yourself the hassle (and shipping costs) and buy something else.
