lugan, thanks for the Lenslet tip.
Your PC having a TPM will suffice for you to get into Trusted Computing! Hopefully it will come with the Wave ETS download. For now that is only available, courtesy of the house, if you request an Intel D865GRH, which would apply only if you replace your motherboard as I can do on my custom built machine, or if you are to have a new custom machine built to your specifications. I hope ETS will eventually come bundled with all box PCs like Dell, HP and IBM.
OT:
Regarding Lenslet, do you have a link? Optics is going to become huge. Besides the possibility of optical computing there is also the hope for pure (non-mechanical) optical switching, without which the world will never see perfect bandwidth on the internet for things like real television-quality live video.
