Beyond the comments over the presentation style, the metaphor, and browser compatibility I want to see more about your specific app. I like how you did the VWO interface on top of his website, you could easily change the line graph section to show the "Intuitive Reports" feature. Line graphs are easy enough to understand so by including more of your value add features it will still stay simple enough.

I know it isn't specifically A/B testing related, but throwing another shoutout to your app at the end like "heatmaps too!" might be nice. It seems people that would look at this slideshow might not be familiar with any web analytics services, and it seems you guys offer many services.
