Jake Ludington's MediaBlab blog just published some pictures comparing a Zune device to an iPod. The iPod, of course, is sleeker and more stylish, having been built by the masters of form, Apple. The Zune is noticably blockier and bigger.
This may come down to the age old form vs. function debate. The Zune specs out with more features than iPod (Wi-Fi, FM radio, etc.), but the iPod looks better and still has enough features for most people. So is Microsoft's Zune an iPod killer? Well, that all depends on whether you lean towards form (iPod) or function (Zune). My guess is that at first, early adopters and techies will buy the Zune for its cool features. It may even catch on beyond the tech arena to some degree. But Microsoft has an uphill battle against Apple to topple the iPod's dominance in the marketplace. They need to pretty it up, because, let's face it, humans are vain creatures who like to look cool.
