Here is a quick hands on I found Nokia Lumia 900 Vs iPhone 4s. It’s not an OS battle just a few random tests nothing really earth shattering just his thoughts on it..yet it is worth watching.
Mind you it doesn’t really seem like the reviewer has a good handle on how a Windows Phone operates. For instance when doing the camera test he is doing it from the unlock screen. When he should have done it from the state of both screens OFF to make it fair.
Also this is just me but the best resolution on a 3.5″ iPhone screen means nothing because it’s a 3.5″ screen. I will take a 4.3″ CBD over a 3.5″ Retina display anyday of the week.
