I had the Incipio red/black originally and liked it so much I bought a black/black too. I've seen varied posts on the black/black and lint issues. I don't see any problem with it on the black/black case that I got and many others say the same thing. Others say it's a big problem and another group seems to say it's a problem at first, then gradually gets better with time. I don't know if different batches attract lint differently or if it's just the environment it's used in, but I honestly don't have any lint issues with either Incipio case I have at all.
There are some pictures I took of the red/black in post #5 above. In my opinion, it is somewhere between red and orange, kind of tangerine or something...but I like it. The Platinum case will fit the extended battery at first, but over time, in my experience with it, the clips wear out and the case starts popping open on one side if you're putting on and removing your case at all. When I use an extended battery in my phone with the Incipio case, I use it without the extended battery door and it works just fine.
