Sure I do think it is a durable top.
But do not think Granite can't warp! That is a common misconception.
If it is not supported correctly it certainly can. I have removed enough Granite off jobs and have seen granite tops so cupped with no cracking it would truly amaze you. BUT on a table saw I do not think cupping would be an issue, but it can be.
If you cracked Granite with a hammer could it crack, I say yes, where a cast iron top would not show or have much damage. But who cracks their table saw with a hammer? If your saw was outside and it froze and then you brought it in and dropped some wood on it could crack it, yes, but again who in the world does that?
I think durability really is not an issue for granite used as tool tops. Is it as durable as cast iron, no, but it is a nice surface and sure is appealing. One company I am not sure who, is talking about inserting metal within the granite to make it magnetic and help it become even stronger, if that ever happened I think I might go for the Granite right away!
The rust is a huge issue and the granite definitely has a plus in that area.
Hey you can get the granite saw now and down the line get an Incra or Biesemeyer fence.
I can tell you want that Granite saw so go and get it!!! Then you can be the go to guy here for info on it.
