Review: Zune HD is no iPod Touch killer just because it’s fairly new but with the time you never know. I think if Zune HD would have camera many would rather buy Zune than iPod Nano!. Zune HD has really cool graphic layout and also the battery capacity is really good too (33 hours listening to music only). I like the fact that it has HDMI port because you can view pictures, videos on your TV or PC, so basically it’s easy to share your images and videos with others.
On the other hand, the Marketplace is so to say empty, but with the time developers will fullfil our wishes with gamesand apps. Over all it has been to little time to say anything negative about it.
