Took it.
Question 14 is still problematic. If you're going to ask about "browsers/search engines" in one question (and I am not sure why you're collapsing them), you need to use check boxes instead of radio buttons. Otherwise, respondents have to make a false choice between (e.g.) Google and Firefox. I for one open up Firefox to browse the web and I use Google as my search engine within Firefox. All of your respondents likely need to select at least two items on your list.
Sorry to be picky, but my background is steeped in both usability and survey design!
