I've read plenty of good books that work outside of the cliches, they're just harder to find.
I'd also say that Fantasy = Magic, SciFi = machines (that's very dumbed down....) and then science fantasy involves a mix of the two ( I made the 3rd genre up, but it fits

)
Do psychic powers cout as magic? Are things that are done, not because they break the laws of nature but because the person has a tremendous understanding of such laws count as magic? (I'm thinking of stuff like the
Dune guild navigators for that one.) Do powers granted by gods count as magic? What if those "gods" are actually just really advanced and powerful aliens?
The game Phantasy Star II seemed to be "science fantasy" under your definition because people use "Techniques" which seem to be magic. However we learn in Phantasy Star IV that magic really does exist and it is something completely seperate from these "techniques." After that revelation, is Phantasy Star II no longer sci-fantasy?
Is Star Wars fantasy because of the Jedi? Is Star Trek because of the Q continuum? Is Warhammer 40k because of the psychics and chaos gods?
That's why I don't like defining science fiction or fantasy based off of technology level or presence of magic. Both are on a continuum and can be varied easily. And we can often omit magic and replace it with highly advanced technology, or vice versa, and end up with pretty much the same story. So I like defining things by how they treat the subject. So for me the genres in science fiction/fantasy are things like the following:
High Fantasy (ex. The Lord of the Rings)
Sword and Sorcery (or Sword and Planet, it's basically the same thing) (ex. the Conan the Barbarian books)
Future History (ex. the Foundation series)
Cyberpunk (which is, of course, close to Steampunk) (ex. Neuromancer)
and so forth.
