The HP/Compaq TC1000 and TC1100 among others have been doing this keyboard thing for some time, though the prop on this unit looks like it may help stability.
I doubt this means anything except that they reserve the right to change the console design at any time before production. To me the sign just says, "final product may differ from what you see here," not "OMG, WE ARE SO SCREWED - we don't even know what to make it look like!"
