Not too much daring on Amiga... I've always been very careful with them... About the riskiest thing I've done is maybe accidently plug a floppy drive cable in upside down or unplug a serial device while the machine was powered up...
Now, my x86 boxes... you name it... Heck just recently, I accidently pulled a graphics card out of a machine that I forgot was plugged in. (ATX-style machines don't really shut off, with the soft-power...) I remembered I hadn't bothered to unplug it as I was removing the card and seeing a green LED on the motherboard still glowing... Didn't seem to harm anything though. (shrug)
Thinking about it, I used to be fairly abusive to my C64s, too... I remember fixing fuses by removing them and replacing them with a small copper wire, and other such nonsense... ;-) I guess it's just the Amigas that get pampered.
