I assume you've noticed this already but just in case it is a quirk of my browser or something, the two panes of your main marquee are of different heights, leading to a little bit of a bounce when you scroll between them.
Also, for what it is worth, in this user's opinion:
1) I'd prefer you disable or hide (probably disable) the green scroll arrows when you are already at the edge of the ribbon. (Ie., when you are on "Apppoinment Reminders" the arrow on the left is gray and disabled while the one on the right is green; when you are on "Who is it for?" the arrow on the left is green while the one the right is gray.) The infinite loop aspect confuses and annoys my reptile brain. I expect to see new content when I click "next". (The fact that your image is a placeholder may be making this worse for me. If I saw the same image crop up again it may be more obvious that this is cycling.)
2) I'd make more of each column on the pricing page clickable. Maybe it just that I'm using a short screen, but scrolling down to the "Sign Up" link seems a pain, especially when it looks as is if "Small Business" is already selected due to the highlight.
3) Personally, I really dislike the green of the Small Business column heading on the pricing page.
Since you're keen on testing, have you user tested the pricing page yet, or is this just a first cut?
