According to Dell, it's not at all apparent that 1.1 machines have been delayed or slowed down by the unavailability of 1.2. This may of course be a smokescreen to conceal Dell's real plans with 1.2, but I don't think the slow launch of 1.1 machines has had anyting to do with waiting around for 1.2. I think the industry is just generally slow in getting any new technology into the market. Evidently SKS was correct in his cc statement.
This is the message to their enterprise customers interested in trusted computing:
• The Latitude D410, D610, D810 and Dell Precision Mobile Workstation M20 and M70 will continue to ship with TPM version 1.1b during the lifecycle of the products. There are no plans to update the TPM to version 1.2 when it becomes available later this year. • Dell may consider launching TPM 1.2 enabled systems with new platform introductions later this year.
