It's too bad it's so hard to pin down a definition, but in practice I feel like most animals with brains experience degrees of qualia. Some mornings after a night of poor sleep when I wake up super-slow I wonder if that's how animals experience thinking.
My biggest problem with "brains are machines" arguments is that there is a risk there is unknown physics at work that is not representable as a Turing machine. What if there is some quantum field effect powering everything?
