Update: Microsoft has hit us with the corrected & updated spec list with a slight change to battery and charge specs: 33 hours of life playing music with no wireless, up to 8.5 hours of video. 3 hours to charge from PC, 2 hours via AC adapter. Hopefully that's long enough to cover your one man rave in the woods far away from A/C outlets. Check the PDF for yourself, but beware, as Microsoft has informed us one typo remains, as the Zune HD can hold up to 22 / 48 hours (16GB / 32GB) of video optimized for the device, no matter what the official sheet says.
