Why is this exactly?
It's cumbersome, a memory and storage space hog, it's slow, the output quality is audibly worse than any other player, it always tries to link me to websites I'm not interested in, it doesn't play well with other software.....

Bloatware. A pain to navigate. Devices notwithstanding, the Zune software is much better. I’m tired of software updates every couple of weeks and especially tired of being offered Safari.
