Interesting, thanks. Do you think one could use only one of the two narrow shelves and put a large screen on it? Can it support the weight? That way you could have keyboard and screen at different heights.
I wonder that as well. Product description mentions only table top, but the construction suggests that shelves also can be mounted at different heights.

If not, I'm sure you can hack it to enable it to do so.
For myself I have a larger discontinued model called the Jerker. It supports large things just fine.
