I went to a BT office once and noted that they were using a Cisco 4000 as a door-stop (which isn't a small doorstop) - the person I was speaking to simply replied that they were the most handy thing around as there are loads of them just sat about under people's desks. So I looked, and yes, there were Cisco 4000's everywhere.
Since this was around 20 years ago they weren't cheap either.
