I find that mostly black wallpaper with splotches of color work best.
I plan on using the live wallpaper that is considered the nexus wallpaper - where the colors move around. I think it looks great.
For some reason mine is on occasion off centered. I do like the fact I have the transparent one. I also love the news and refreshing like you.
The transparent one rocks, that's what I also use. However, I had to change my wallpaper because I couldn't read it and couldn't change the white letters. That was the only drawback for me.
Sorry, I've been up all night, but is the text that you've quoted from someone who's using the ported ROM, or someone who already got the update? [Just wanna know if I should start being jealous of people who've already got the official update...Haha!]
