Battery life is 12~14 hrs for music playback on one charge. And no the zune will not work as a mass storage device for storing other files. That only worked in the earlier 2.0 firmware. Natively it only supports wmv videos, but if you get one of the converters it can play any video.Quad Master said:General Doubt.
How is the battery life.
Does the zune work as mass storage device for storing other files.
What video formats does it support.
