If you were this close to snapping up a new Zune after Microsoft pushed out its 3.1 software update, boy, are you glad you held off. At least, if you've been eying a Zune of the flash-based variety. Beginning today, the US Zunes are coming a little more in line with their Canadian brethren by falling from $129 to $99 (4GB), $149 to $139 (8GB) and $199 to $179 (16GB). The Car Pack / Dock Pack are also seeing a $10 decrease while the Home / AV pack is being reduced $20. You already purchased two in the time it took to read this, didn't you?
