How long do coils last?

I've got my original coils on my 08 with 64K miles on it. Not tuned. I'm getting what feels like light stuttering or misfires (rough acceleration) under WOT at higher rpm, especially going up a hill. Although it does not seem to affect performance (still pulls strong).

Had the carbon cleared out 20K ago and the plugs changed 10K ago. I understand it might be a coil, but before I go and troubleshoot it down to a specific coil should I just be looking at changing all of them due to age?

How long do you think our coils are good for?
