The advent of Windows Phone 7 brings with it a drastic reduction in unnecessary elements including the lack of a customizable wallpaper. Instead, we have a black or white background depending on the theme. I have to admit that at first I thought it was a big mistake but, I have grown fond of the minimalistic approach. With that in mind, Pocketnow.com has a great post that has a mock up of the windows start screen with a background wallpaper. I think it does look good but as I said earlier, I prefer the more minimal, no background look since the live tiles make up for it. What do you guys think?
