smoothness. generally speaking, drilling/cutting methods from thousands of years ago left very discernable grooves.
@fram: yes, i suppose i should have said "barely acheivable with recent technology." laser drilling and cutting, as well as water-jet technology (which i did work with in the early 90s at UMR), offer extremely smooth cuts. however, only a couple decades ago, this was difficult even for us.
either way, yes, it is really tough to fathom a civilization capable of such things several thousand years prior to our own capability.

That's funny. Stonecutters have been producing smooth and flat surfaces on marble and granite blocks for centuries. Visit an old graveyard in New England some time and check out the near Grade B surface plate faces on some of the stones from the 1600s.
Re the smoothness (i.e., surface finish) and flatness of the Egyptian blocks, this was discussed in detail in
this thread. There's nothing extraordinary about the Egyptian blocks, except as examples of some of the first large-scale applications of technology to materials by human beings.
