All Apple on Intel machines have TPM, that's what 6 percent of new  
PCs?

To nit pick, the TPM is only present in some Apple Intel
machines and isn't used in any of them. See
http://osxbook.com/book/bonus/chapter10/tpm/

Their OS decryption key is just stored in normal firmware,
unprotected AIUI.

They've apparently stopped shipping TPMs. There isn't one on my  
MacBook Pro from last November, and it is missing on my wife's new  
Santa Rosa machine.

If you want to see if a machine has one, then the command:

sudo ioreg -w 0 | grep -i tpm

should give something meaningful. Mine reports the existence of  
ApplePCISlotPM, but that's not the same thing.
