faacfi,
This software is an excellent way to see a Boeing flight deck automation in action.
I found it invaluable when my Australian ATPL instructor used it in conjunction with a projection screen to illustrate automated flight, following lectures on the subject.
Some things you cannot learn from diagrams in a book -- this was definitely the best way to see how the autopilot modes worked, and you could try things for yourself.
However, after an hour or so, we all got the idea. After all the system must be simple if airline pilots are to use it
Despite this excellent ability, I decided that the cost was too high. Also, after you get the idea you will probably not use it again until you possibly get invited to interview for an airline that uses Boeing aircraft. If you have some amenable class mates, why not pool your resources and buy one copy between yourselves?
