to be fair, the whole of their site seems responsive, not just the landing page.
It also seems to load pretty quickly over 3G - so they've been economical with the resources tool. My biggest concern would have been that they went overboard with Javascript libraries to make the page map equally well on the mobile as it does on the desktop - only to forget that mobile bandwidth is generally shite. But that doesn't seem to be an issue here.

All in all, they've done an impressive job.
