I bought a Belkin Remix Acrylic Case for Zune 80GB/120GB
and did not really like it that much. I wasn't fond of the metallic front, it made the Zune pretty bulky, and I could never get the screen protection to not make rainbowy effects on the screen when looking straight on (not visible when screen is on, but still bugged me to some extent). Furthermore, it was very difficult to access the hold switch (only my pinky fingernail could work).
I ended up buying a different acrylic case (this one
) and I like it a lot more even though it was cheaper and feels a little more cheaply made. The hold switch is easier to access, there's no metallic front (and because it's smoke colored, it further retains the blackness of the Zune better), and it's slimmer so it doesn't add too much bulk to the Zune. The buttons are protected now (not that important to me), but the Zune squircle is easier to use now vs. the Belkin case. The screen when viewed at extreme angles shows a lot of rainbowy effects, but when looking straight on it's crystal clear so far (*crosses fingers*).
The smoke case came with a belt clip and lanyard thing but I didn't bother trying them. I actually ended up trying the Belkin belt clip first and it works pretty well. It actually snaps on tighter to this case than the original Belkin case. It still retains its function as a belt clip and kickstand as shown in the first two pictures below.
All in all, I spent about $15 for the Belkin case and $6 for the smoke case, but in the end I made a hybrid case using the belt clip from the Belkin and the actual snap on case from the other one and I'm pretty satisfied with how it turned out.
