I don't see this as unethical because there is still the possibility that they will give you an offer that you would consider. It's just that they'd probably have to offer quite a bit in terms of compensation and opportunity to actually make you budge if you're happy with your current job. Although, I have never done it either. I've always been too busy at work, and I view the dishonest aspect as the potential lie I have to make up to take off a day from my current job to go interview.
