Running and testing beta hardware and software is second nature for me at this point. I do it for this site now, as I have regularly since iOS 5. I actually do it quite often at work. My background is in programming and systems integration, so I used to test my own programs, as well as things developed by others. I still do from time to time I do a lot of beta hardware testing at work these days, which is a different kind of challenge. All this to say that, whether at work or on my own time, I know full well that anything with a beta tag can bite you in various ways.
