Yep, I still find myself switching to the old version so I can get terrain view. In the new version, once you type in an address the "terrain" link below the address box disappears. I can't imagine why that is supposed to be helpful. My typical use case is that I click a map link for a hike, enter my address to see how long the drive is, and then want to switch to terrain view to see terrain for the hike. Apparently, that is no longer possible.
