On my Macbook Air, I didn't even realize there was something below the fold. I was scrolling side to side and clicking on the icon, trying to figure out what to do (partly the fault of Lion's disappearing scrollbars). The min-width of 1280px seems unnecessarily wide. Scanning right to left and back again to read what your company does is not the most pleasant experience.
Is your browser not open to full width and height? I'm on an 11" MBA, and didn't have to horizontally scroll at all (at 1366px wide), and I could see the end of the fold easily.
Regarding the disappearing scrollbars, I've actually added prompts for scrolling to a website, knowing that Lion, iOS and Android users wouldn't get a hint from visible scrollbars. (My biggest issue is the way horizontal scroll is so easily misinterpreted as a swipe [chrome in lion]. At least a few times a week I inadvertently go back a page...)
After about 10 seconds of not finding anything (even with a horizontal scroll), I gave up ... and didn't learn there was more below the fold until I (re)checked the comments here.
