Battery Issue

The biggest feature on Zune, the Wi-Fi , seems to require more power than expected, may have an issue on the battery life. The Sony PSP lasts about 45 minutes when Wi-Fi is turned on. How long can Zune last?

Some analysts are skeptical that Zune player will have the capability for a longer battery life. Microsoft has not offered specifics of the products yet. This issue has to be solved before they can battle against Apple, not just to take a huge step, but to break in the protable player market where Apple dominates.
