Now this is distinctly not good. According to David Berlind, Microsoft has confirmed to him that certain features of Windows Vista will require a Trusted Computing Module to work – and specifically, a version of the TPM chip that isn’t currently in any systems.
The TPM requirement should give system buyers — particularly those in enterprises — a reason to pause before buring their end of year budgets on a bunch of new systems that could be obsolete by the time Vista ships. It largely depends on what the full list of TPM-reliant features looks like (if there’s more than just full volume encryption), and which of those features enteprises will be depending on for tighter security.
Ignore, though, the comments, which are the typical anti-TPM hysteria ("Microsoft will own your data", "DRM crap" etc etc). This aspect of TPM is nothing to do with DRM or owning your data: it’s about being able to ensure that no one – not even MS – can get at your data without your say-so, even if you lose the hard drive. And that’s got to be a good thing.
