PC World took a look at the ultraportable Lenovo ThinkPad X41 notebook, here's a short snip from their reviewage:

Lenovo's (formerly IBM's) 3-pound ThinkPad now has a fingerprint reader. The skinny rectangular slide sensor is embedded in the palm rest just beneath the mouse buttons. Biometric software walks you through the stages of enrolling the finger of your choice; thereafter, a single swipe replaces typing in multiple user names and passwords at the Windows log-on and at Web sites.
