(my "insane" comment was about the market reaction to the TPM, to clarify)
No, I mean the general design of the security model. My phone, for example, I think is far more securely designed than my PC, from the security model of the OS, to the hardware.
Windows probably has to turn the security down a little bit or the average user will complain about how difficult installing software is (the sort of user who would run Linux as root all the time). I don't know if Windows has the right foundations either, maybe it's mostly misused and the #1 target which makes it more exposed than most other OSes. I haven't tried to understand how security was implemented in the recent versions.
I thought you meant TPM would mainly add support for hardware authentication. I don't like the idea of locking all software to one hardware platform, I rather believe in locking it to an individual on multiple platforms. TPM could actually be used for that too. So let's hope that's the direction they'll take.
As for the OS, I want to be able to reinstall it, or to move it to another computer or a modified computer if I need to. But this is not possible anymore with Windows, except if you bought Windows yourself and if you call MS to get the authorization to uninstall/reinstall it. Since most computers cannot be bought without Windows, which means OEM, they're unmovable.
PS: just saw TPM modules had a true random number generator too! Nice. Hey, maybe it can be used for RPGs
Since the context here is TPM, that's definitely not what he means.
Ripper had already answered just above. But it wasn't that obvious, TPM has a lot of uses, I don't see why it couldn't be used to prevent piracy. It's actually the perfect tool for that.
EDIT: when I say "perfect tool", I mean the idea of it, not its current implementation
