I'm driving down to Oklahoma from Minnesota in July and need to get the CarPC reinstalled since I really hate not having it and this trip would be a great stress test for my install. My 8" lilliput died a while ago and I just haven't gotten a chance to replace it. I would like to keep with an 8" widescreen but I'm open to a 7". After having my lilliput mirror installed I'm thinking capacitive would net better results. What are the community opinions?
