There's no way of telling whether or not this is the rumored Zune phone's interface, but the guys at Mad4Mobiles recently dug up this MS patent that shows what looks like a smartphone interface. The interface has icons for TV, music, weather, and shopping. Personally I think it looks a little too cluttered, but if this is indeed the Zune phone interface, it looks like it'll be packed with features. – Louis Ramirez
New Patent Shows Possible Zune Phone Tiled Interface [Mad4Mobiles]

译文:
微软ZunePhone使用界面终于现世?
我们没有什么证据可以表明这就是传说中的ZunePhone的界面,但是Mad4Mobiles的一些家伙最近发现了微软申请了这样一个极其像是SmartPhone界面的专利。在这个界面上我们可以看到电视、音乐播放器、天气和购物等图标。我个人认为这个看上去实在是有那么一点乱糟糟的,不过如果这个确实就是ZunePhone的人机交互界面,那么很有可能它会整合这些功能。-Louis Ramirez
