I am still using my first intellimouse; it must be 15 years old (I actually don't remember exactly when I bought it, but it was a long time ago) - it's absolutely perfect still. I have just ordered another for home (just in case) and two for the office (one for usage, one for backup). It really is a solid bit of kit, and I'd be gutted if I couldn't source one again.
