questions about the iriver clix gen2 and creative ZEN

Keep an eye out on the Sansa View too
it's gonna be competing in that market level and the price is awesome

1) From what I know, the iriver clix doesn't support that many video files so I'm not too sure about it... however, the creative zen has one of the best video support in my opinion. Whatever I throw into it, it plays with absolutely no problems.
2) For sound quality, I'm really on the fence with this one because they're both recognized to have good sound quality.
3) I think the video qualities are almost identical to eachother but since the iriver's screen is 2.2" compared to creative's 2.5", I'd recommend that latter.
4) Both of the players are known to be pretty userfriendly. For this though, I'd go w/ the iriver clix 2g. The navigation is simply genius. Both of them can create playlists and change wallpapers as well.
5)Clix - Can create your own themes! Praised sound quality and a gorgeous screen which will have absolutely no glares out on sunlight.
Zen - Video file support is amazing. Sound quality is almost as good as the clix I think (not too sure). Navigation is pretty good as well.

Overall, I'd still recommend the zen because it doesn't limit you. You can have expandable memory while the clix can't. They're both designed pretty well and overall, I think the zen will last you longer.
