Being a shades of grey person myself I'd say why bother differentiating anyway?
A lot of attempts have been made to draw a hard-and-fast line between the two, but the history of the genre(s) doesn't really allow of that. There's also the hybrid genre science fantasy, exemplified by the likes (at least at times) of A. Merritt, H. P. Lovecraft, C. L. Moore, Andre Norton, Rod Serling, Michael Moorcock, etc....
I used to read a lot of Andre Norton, and I think he does blend the two genres nicely.
Oh, sure it does. Everyone under the sun has their own little ways of categorizing books and movies. One method wont work for everything, so all we have to do is invent new terms, like "steampunk" and things like that. But the fact is that most of everything in either genre can be easily categorized, so I'd say on the whole that the genres do allow for that. Its just a relative minority of odd balls we have to work with to nail down, and even when we can't easily do so, trying is fun.

I'd say SF uses electronics, whereas fantasy uses dwarves.
I am going to write a book about Dwarves using Electronics and then where will we be in this conversation?
