I generally don't update firmware ever unless there is a problem. One exception is bios. Then if I have the occassional mysterious freeze/reboot I'll try it. Also if there is something like known ram size or particular hardware fix. But I can count those on 1 hand over 20 years. Also I suppose there are cases when you bought stuff just as it came out, there can be useful firmware updates after the first several months it is on the market.
