It hasn't been there on all new systems purchased in the last 3
years. My laptop is about 3 years old and doesn't have AES-NI.
Neither does my file server (1.5 years old, AMD CPU, IIRC.) nor my
mobile phone, iPad, last year's MacBook Air, etc.
This is, of course, annecdotal evidence, but I do not think that
I am an entirely atypical consumer and yet I do not think that I've
ever owned a system with AES-NI.
I do not think that it is nearly as prevalent as you believe.
