In another of Ryan Rea’s “1 a day interviews” with his “source” he has posted:

RR With Tegra in the Zune HD… what kind of battery. life are we looking at? TK it should be roughly 5X more then the current iPod touch

Now, if this is true.. that’s putting the zune HD at roughly 7.5 DAYS of audio playback, and 30 hours of video. Impressive. This number seems incredibly high, but with Nvidia Tegra and an OLED screen, it could be a possibilty. We’ll have to wait and see…

Next came Cnet’s first look…

And finally Engadget checks it out.
