This is just a question I'm asking out of curiosity. I'm not endorsing or advising anything, but from a purely technical standpoint, does Apple gain anything from having lots of non-dev testers? Obviously there are quite a few out there, and I just wonder if any good data comes in, since these people aren't going to be sending in any actual bug reports. For instance, do you think the automatic diagnostic reports do much good, as far as testing the OS and identifying problems goes?
