I thought of the same thing. I am constantly between 4k and 4.5K (I would 
appreciate it if nobody did the math to convert to mph! :)

I heard the same thing, that they dont last if pushed past 3500, but I 
never heard of them shutting down. Mine has been hanging in there for 
quite some time now, so I dont beleive any of it.  My old 4000Q which was 
geared lower whined faster and that one lasted 300K.

What does that tell you?
