Virtually nothing will protect you from people who have access to your desk. It takes only seconds to install a trojan: less time than the time-out on your password-protected screen saver. You're vulnerable unless you explicitly turn it on every time you leave your desk. Usb key loggers are easy to install and conceal, as are web cams that can watch you typing your passwords. If your cpu chassis is accessible after you leave for the day, an attacker can install a trojan even if you are methodical about locking your desktop. Whole-disk encryption can help. But who goes to all these lengths? Physical access trumps all.
I use a laptop, and lock it in a drawer when it's not in my possession. But I don't imagine that I'm invulnerable.
