[1] The Zune to Zune sharing feature may not be available for all audio files on your device, and works only between Zune devices within wireless range of each other. This feature allows recipients to play full-length sample tracks up to 3 times in 3 days.  Recipients cannot re-send music that they have received via the sharing feature.

[2] Batteries have a limited number of charge cycles and may eventually hold less charge. Battery life and the number of charge cycles vary by use and settings.

[3] Zune software can import audio files in unprotected .WMA, MP3, AAC; photos in JPEG; and videos in .WMV, MPEG-4, H.264.
