likely buyer for the same reasons you don't like it.
I also consider myself an abuser of camera bodies, and some of the same points you list as negatives look very much like positives to me, perhaps due to a different use-case. You're probably right that you're NOT the target market for this camera, and Canon want you to buy the 7D instead, but I still think think some of your objections are spurious.
Body strength: If you truly drop your camera often enough that you're worried about breaking the body, and you take yourself even half seriously as a photographer, your budget for replacing damaged lenses must be phenomenal...
Swivel screen: may be an insta-break if you're into dropping your camera, or grabbing it by whatever protrusion is nearest, but if you think a swivel screen is such a bad idea, you don't have to use it that way - it's very unlikely to break when it's folded in!
From my POV (pun intended) a swivel screen would be an incredible boon for composition in difficult spaces, and the option to have it LCD-inwards protects the LCD from scratches the rest of the time when composing through the viewfinder.
And while I can see that many photographers couldn't care less about a little extra weight or bulk, to me a lighter (and smaller) body means I can take it places where taking another camera increases personal risk or at the very least discomfort; down canyons, up mountains and rock climbs, travelling out of the way places. Steel chassis/plastic body construction is plenty strong enough for me, and I've been shooting outdoor activities since before the label "extreme" was applied to anything and everything, back when camera religion was as much KR64 vs Velvia as Nikon vs Canon. The only reason I use an entry-level body is size and weight, this being equal I would have bought a high-level prosumer camera years ago.
