I went with the blue, my sister went with white. I was debating white because of the versatility with cases (as most people have stated). But it's not like I like very many colors. The blue looks good with black, grey, white or purple. I'm not into the pinks and warmer toned colors. I can see how some shades of blue would look awful with it. I bought a purple case, still waiting to see how nice it'll look (probably pretty nice). I had a little blue Exhibit II and had a transparent purple TPU case. I liked how it looked.
I also liked the "brushed metal" look. It makes it different. White is just white. If it was pearlescent or something, maybe I would have gotten white.
I almost regretted my decision after looking at cases, but after a few days with it in it's naked state, I think I made the right decision.
