The corner units have built-in keyboard trays with good adjustability, so I was able to get work done for the first week or so, but it wasn't a long-term solution. So, I pulled all of the cube furniture out of my cube, and also lowered one of the partition walls to about 3 feet high. I found a furniture piece that's intended to cover lateral file cabinets to use as a desk and installed it at a more reasonable keyboard height. The monitor stands allow adjusting them very very low, so I put them on top of the 36" cubewall. Now I have actual workspace, and there's room there for two people to sit and see the screen:

Next up will be to swap parts between the two bookshelf things to make a single low, wide bookshelf/drawer unit which can roll under the desk, and put a couch in the space currently occupied by the bookshelves.
