We know that the all the E series notebooks and all but one desktop are TPM 1.2 equipped. The S series is for small businesses and perhaps is at the low end of the scale. I'm still trying to find out, but it would seem that for the slight increase in price it would of been rather foolish not to include one. You'd think it would of been in the PR if the TPM was included though!
