I keep reading anecdotes like this, and it gets me worried about the day I buy a mini (which should be soon). I have used the wireless Apple keyboards for over a decade on my various iMacs, and they've been rock solid every time. I don't even think about it. Is there some kind of strange difference between iMacs and the Mac Mini when it comes to bluetooth peripherals, or is it just the non-OEM boards, or are you an outlier? Maybe the Mac's keyboards are just better for bluetooth. Heck, I use an old mac bluetooth keyboard with my work PC and it never fails. I want to know if I'm normal or just immensely lucky.
