I don't have 80M for 06 PC deployments. I have a conservative 50M with the majority of TPMs being turned on at the end of the year and 50% wave involvement with $10 per ETS seat. I think the reason my numbers are higher is that in your model you ignore the legacy PC activations for those that bought a TPM pc but didn't originally buy ETS. I think as those quarterly deployed PC numbers stack up, a small activation rate of maybe 10% over the year will be staggering.
For 80M TPMs deployed, 64M with wave, that would leave 60.8M TPM pcs. You are assuming they are never activated. If only 10% bought wave with a $10 profit to Wave, that's an additional $60M in revenue for the year.
