eamonnshute, if you need to upgrade go ahead and do it. Most computer security companies will even deny that TPM exists. Formally there might be even right because the number of installed TPM networks is as good as insignificant yet. Nevertheless their reasoning is based mostly on their own business which is partly or completely threaten by TPM. The worse side of the issue is the fact that they control just about everything in the security area and based on their installed base and on their newer and better products there is a lot of brainwashing going on to convince their customers that the status quo is ok. The consequence is that so far there was no massive rush toward TPM and there will be hardly one in the near future. TPM is an uphill battle and the fact that Wave is finally out with real products does not mean an instant great win. having the industry behind and more and more complex network architectures ahead TPM should be in time a real winner.
