Remember, the red is glossy. I much prefer the matte and thats why I went with white. You can always get a case but it would be harder to cover the red.
I agree with michaelkriss, I would pretty much be satisfied with anything not the red (preferably white and considerably yellow). For a variety of reasons, the glossiness just doesn't cut it for me.
I doubt you wanna do that. Considering the land mass of the phone, with just a skin/clear case, if this phone should ever fall, you would wish you had a better case on.
I have seen a lot of people in the forums with this regret. And fixing the screen/digitizer could be pretty facking expensive, and not just any repair guy can fix it.
