Granite vs Steel top for table saw

i am shopping for a new ts and ran across an ad for a granite top table saw from steel city. i read the review here on lj and my immediate reaction was, i dont want one, but the review mentioned nothing about the performance of the granite top vs a steel top. anyone here have any experience with the granite tops? what are the advantages and dis-advantages? with my luck, i would break the top before i even get to use it…....<g>
