cheap (used), durable and quick to turn on
Thought you were looking for a woman there.
I agree about compact cameras with telescopic zoom being a bit slow.
The Nikon 1 cameras with a fixed or short zoom lens comes on pretty quick, like 2s ready to shoot, image quality isn't as good as a DSLR, though less faffy than a phone camera.
Unless size was important I'd still probably go for something like a basic canon/Nikon DSLR with either a decent fixed lens (2.8 35mm on a crop sensor) or short zoom (usual is 18-55).
You can leave it switched on in sleep mode and usually ready to shoot in 2s, I think my old Nikon d60 took 3-4s to turn on and ready.
