thought I would share that I was at the mall today and went to one of the few Dell stores here in the Chicago area. I was shopping for a new PC for my mother's company. The Dell store only sold consumer PCs, but I mentioned the Latitude and he knew all about it.
Dell guy said, "I can probably get you an Inspiron with the same options for cheaper."
I said, "But they don't have the TPM chip."
Dell guy said, (to my amazement), "Yeah, that's the primary difference between the two."
I nearly fainted! He knew what a TPM was...
