I have the older 725, looks the same aside from fewer pixels.
I've been very pleased with it. Very light and compact so fits into a pocket and is genuinely waterproof (I needed something I could take kayaking that didn't object to being underwater in an unplanned manner). I haven't tested the shock-proofing, and don't intend to!
Battery life is good. I carry a spare but have never needed it yet (even away for a week, though I'm not a prolific photographer). The pictures are okay, I guess... not being a photographer I wouldn't like to say, but at my level of snapper rather than auteur they're fine, better than my old 35mm Olympus XA3.
The only real Gotcha is there's no viewfinder, just the LCD screen, and it can be problematical seeing exactly what you're shooting in bright light conditons. That is a genuine downside, but a viewfinder would mean more weight and more bulk so you'd lose one of the best aspects of the camera if you cured it.
Exec summary, if I lost it, i'd get another (or probably the newer 1030).
