Windows Phone 7

Im looking at either getting an iPhone 4 or the Windows Phone 7… seen the iPhone 4 in action but as im an Xbox user ive heard you can use Xbox Live on the windows phone, etc.

Does anyone own one?.. is it good?!

before getting an Iphone watch this informationaly video…

Have you considered the blackberry torch? I wanted a Iphone 4/ HTC, but after trying the torch i thought it was better than a Iphone.
