Sure, I have had many 8700c's that I setup for clients of mine, and the vibrate is a little different on each, same with keyboard, some units vibrate stronger, and some keyboards are easier to type meaning some are raised more and some feel harder than others to press...
After having the 8700c for 2 days, I am really delighted with the "silent" vibrate. I know longer get strange looks during meetings and don't wake up the neighbors in the middle of the night ;)
