Actually you can go into Settings> Sound and Display and uncheck haptic feedback, if that's all you need to do. Spare parts does do a lot more than that.

 

It can also be disabled by pressing Menu>Settings>Sound & display>Uncheck the Haptic feedback box

 

Why would you want to disable haptic feedback on the touch keys? just curious to know

 

I'd like to know as well... I thought haptic feedback was pretty cool when I messed with the Instinct HD and was a bit dissapointed that it wasn't as substantial on the Droid -- much less have it disabled completely...

 

I had it on for about a month. I have it off now. I don't really have a reason why except I like the clean feel of just pushing an icon and having it respond. I like the idea that I can turn it back on again if I change my mind.
