I recently entered the world of high-end mousing. I have to say, I'm impressed, and wonder how I ever got along without it.
The Razer Pro|Click V1.6 feels good in the hand, is smooth and accurate, the buttons have great action, the software driver has a "sensitivity adjust on the fly" feature that is wonderful, and the thing is just plain cool looking too.
I had to migrate a multi-site installation of Drupal from one server to another, and devised a way to copy all the relevant MySQL databases from the old server to the new server with a single bash command. It is secure as it is piped through SSH. Hope someone finds this useful.
