nieske writes, "Engadget reports that Wal-Mart accidentally published online the intended price of the Microsoft Zune; the iPod rival would apparently retail for $284. The price was quickly pulled from the Wal-Mart site. Reports say that Microsoft was flustered when Apple dropped the price for the iPod 30 GB, previously $299, to $249. BetaNews states that 'undercutting the iPod is a major goal of Microsoft's upcoming effort.' Will Microsoft respond to Apple with another price drop?"
