My point isn't that liquid can't accidently get into the cMP enclosure. My point is that it's less likely to happen compared to an open top design such as that used in the nMP
I agree that it's less likely to happen with the old design than the new; but I don't agree that it is a "design flaw" or that it is a big enough problem, statistically speaking, that the design needs to be changed to be less susceptible to liquid spills.
