I don't think case hardened is a good choice for a machine table that will inevitably be cut and drilled into.
Also, no larger central opening for through holes. Not sure what this offers over traditional fence and t-tracks or slots.
It looks like welding table, but unlike welding table you don't need to hold multiple pieces in perfect alignment while you work. It's one part at a time.
That was my bit of rain on the parade.
