I was going to leave a comment in my last post answering questions, but I decided to make a new one.
So first off, we're not announcing availability or launch date today. And we're not announcing price. But I can tell you to wait till you see it officially, and that Zune will be competitively priced . . .
On Zune file formats: Zune will support your existing, unprotected, music library (MP3, AAC and WMA files), as well as video formats (WMV, H.264, MPEG4, 320x240), and JPG photo files.
We're still testing battery life, so I can't give you a definitive answer. When it's final, I'll post, and I'll get you info on how long Zune takes to charge.
Zune will play podcasts. I'm actually listenting to a podcast right now. If you bring the audio file into the software (like a wma or mp3 file), you can play it on your Zune. Beyond that, there will be other options for podcasting support for future releases.
<edit Tuesday Sep 19> I clarified how DRM works on Zune in this post. Mea culpa.
You can plug your Zune device into your Xbox 360 to stream music, pictures, and video, via USB cable. Get all your Zune content on the TV in your living room. Also, when Zune launches, foks who also have a Media Center Edition 2005 PC will be able to access and play any music they downloaded from Zune Marketplace. You can access this music just like they would their regular music libraries – in Media Center’s “My Music” folder. This music will playback just like other songs in your library. Oh, and the Points you have in Xbox Live will transfer to Zune (you need the same passport). They're Microsoft Points.
