Yes, there are some uniquely irritating things about it, but on the whole I'd give it the thumbs-up.
I would have more confidence in the spell-check function, though, if, once a document has been processed, the blasted thing didn't come up with a message which says:

Good to go?
Good to go????
Would the wretched program have told Shakespeare he was good to go after he'd just killed off just about everyone at the end of Hamlet?
