I'd say you pretty much nailed it. As far as I am concerned, granite
saw tops are pretty much a marketing gimmick. It would be about the
last thing I would look for if I was in the market for a new saw, which
I'm not...I'm currently restoring a 1949 Unisaw, and when it's finished
it'll join my 1965 Delta 12/14" table saw in my shop as my daily drivers.
