It appears that the new icons I developed are having mixed results.  About 1% less people (9.5 -> 8.5) click on the download free trial button, although the overall conversion has stayed constant since the textual links are picking up the slack.  2% more people (1 -> 3) are clicking the Buy Now! button.  I’m not entirely sure whether that is a result of just the redesigned buttons or the result of changing Purchase Now to Buy Now! but either way, what can I say, I like it.  Hope it keeps up.
