Looks good. Even though your domain name says faq, I would still put in a intro paragraph to tell visitors about your site. Some of these other points you probably already have on your "to do" list 1. Center the page. 2. More pictures of the models. Example: Show a Dyson Animal vs a Dyson 17 3. Make your site width the same as your header width (one line about 1/3 of the way down is running over) 4. Use a darker perimeter background color. Right now its a white on top of a very light gray.
Make the width of your table smaller so that it's the same width as your header (there's too much white space on the right of your site). Header design is neat..
I agree about the massive white space on the right and more pics. Maybe there's a Dyson video you could add? All in all, great start, cool niche!
Several questions are doubled, it might be a good idea to use the two columns layout instead of the one column one.
