Yes. Like you mentioned, the Zune is a first release, so I'm not entirely sure I'd want to go out and buy one not knowing exactly how reliable it is...I'm simply stating I think it has good potential, and that I have heard very few negative comments about it so far...
I'm just saying that in addition, I would definitely trust a Zen, since I've owned a creative mp3 player which worked perfectly as long as Ive had it (as far as I know, it still works)
