One of the things I love from my new "friend of work" Thinkpad notebook (as you know, I was forced to change my old and lovely Sony Vaio 
) is that it's a solid machine really built for a professional usage, so no gadgets but a rocky case with all the security features you need on your work.
But there's a feature that makes these lines of Thinkpad notebooks particular: they have an integrated fingerprint reader.
Instead of having password for Windows access, for BIOS, for wireless authentication or for access websites, you can register you fingerprints and use them to have an authenticated access. You can set up fingerprints for every user and the software will recognize them securely.
Why not having these types of authentication features on every pc now? We live in an era where security is a must to have and fingerprint readers is a technology that was launched many years ago. Why only IBM (or Lenovo now) are using it on their professional series of products?
Hardware manufacturers, this could be a value added for your products so... start think on this
