I agree with all the comments above.
I've attached a screenie to show that I too see the screens out of the boxes on the right. I am using Firefox 3.5.7 on Mac, but it's the same on Windows Firefox. Broken on Safari (Windows & Mac) too, and Chrome on Windows. Using Adobe Browserlab, I can also see that it's not right on IE6, the screens are in the box, but the box is pushed down underneath your paragraphs. Seems fine in IE 7 and 8 though.
Not keen on the condensed header font. Another thing I would consider is increasing the leading and decreasing the measure of your paragraphs. They are a bit unwieldy at the moment.
And more areas need to be clickable, as mentioned above. The Marketing, Live Chat, Branding boxes need to lead somewhere, the logos could do with it (change them for ones that can lead to a case study if these ones can't?) and the big call to action "You need to act NOW!..." needs a larger click area than the "click here" text.
Hope that's helpful
