Dory, VH.....first the 20M figure means ETSL by Dell, GTW, Intel and doesn´t include the ESC chip bundles. Second IFX chips are on MOST Asian OEMs right now, what doesn´t mean, that the TPM suite is installed or delivered with the machine. In fact I had several IFX equipped machines in hand and NOT a SINGLE ONE had the software preinstalled! Most OEMS didn´t even ship a CD with the IFX TPM software.
So my guess is that IFX ships at least the same TPM quantity as the other TPM manufacturers combined, but their installed base of TPM management software is just about 10% of Waves figures.
