I think a much more enlightening poll question would be:
"If it weren't for your NANDroid backup(s), how many times would your phone be permanently bricked?
For most of us, I think that number would be too high to recall
And whenever I start tinkering with custom ROMs, I take off my otterbox case. Cause I know I'm going to bootloop/crash it at some point and will need to pull the battery.
I guess it's too much to ask for a hardware reset, like power + vol-down anytime during the phone's operation...
