As you could see in my 'Post your workspace' thread, I have the following for a keyboard mouse:
- Macbook

- Saitek Eclipse II backlit keyboard
- Logitch MX510 mouse
What do you use on your computer? I have a MX3000 keyboard/mouse combo sitting around, but the L key doesn't work. I'm thinking of taking out the mouse and using that, because my MX510 is buggy with my new desk (I have to use a mousepad unlike my old desk which the mouse just worked on the wood, and my new mousepad doesn't work at all).
