If it is enclosed like a cabinet saw, and the top adjusts like a cabinet
saw, then why isn't it a cabinet saw; albeit one with a small motor?

Because it has a contractor saw trunnion. And not all Hybrids adjust the
top like the cabinet saw. I only know of the Craftsman that has a cabinet
mounted trunnion. The Delta has a top mounted trunnion like a contractors
saw. Not sure about the others.

You really should check out www.woodnet.net forums. This same subject gets
beat to death every 6 months or so on that site. Should be lots of info
there. Especially the Delta vs. Craftsman debate.
