MacBook Pro trackpad clicking intermittently broken

So when I got my new MacBook Pro (late 2008 edition) with the fancy new trackpad that is an integrated mouse button, it had an incredibly annoying problem:  every 4th or 5th click, didn’t click!  So I’d be clicking on a window behind the current one, or clicking on an icon in the dock, and it would sometimes take two or three clicks to switch to the window or app.  After checking in with Apple (and unfortunately 2 hours on the phone walking through all sorts of different options), they ended up sending me out a new MacBook Pro.  The new one arrived yesterday and after a fairly straightforward migration (only the printer driver for my Canon MX850 didn’t automatically migrate), I now have laptop with a properly clicking trackpad.So, if you have this problem, you at least have my experience telling that it’s a hardware not a software problem.
