Jason, I agree with you and all you have said here. But this comment is the one that hits home the most with me.

I think way too many people see higher resolution as the same thing as being more accurate.

It's kind of like the use of a refractometer over a hydrometer. I 'calibrated' 2 hydrometers to a calibrated refractometer some 5 or 6 years ago. Both hydrometers were not accurate. So I marked each with the error rate, one read 0.005 to low and the other was 0.003 to low. For several years I used the hydrometers and every 3 or 4 months I'd double check them with a freshly calibrated refractometer. Occasionally the refractometer needed a slight adjustment to be accurate, but the hydrometers always have the exact same error rate as they did the very first time I tested them. Yet many people say hydrometers are junk. If it has finer resolution and/or costs more, it must be better...
