The webpage looks clean. The ratios of graphic elements to their scale is pleasant. The two-tone color palette is pleasant. The line length in the main screen (~140 c/l) is a bit much for my taste.
As far as the Try now, I'm not sure how these relate to each other. Maybe a video demo walk-through taking one technology, such as the digital watch (which we are all familiar) and walking it through the site?
As a "Try now" user, until I can throw in any random data and see it propagate through your product, I won't realize what you've accomplished.
