I'm not sure how you've figured these timelines, but I don't quite see it that way. If a company was buying computers with TPMs, they would purchase a sufficient number in the first buying cycle to do something with them. I agree that it would take roughly 3 years for almost all the computers to be upgraded. Once they decdied to do something with the TPMs, they would start purchasing client and server software to make this happen. I don't see one year transpiring from the time they have purchased TPM computers, to purchasing any software to utilize the features. Of course I am assuming that with 25% to 30%of TPM enabled computers with users that the company would wish to better secure them.
