I figured that ATMOS has been implemented for a while now, so most of us have experienced ATMOS enough to know how we feel about ATMOS.
If we think ATMOS is a huge improvement or is very fun and exciting, then we may want to implement ATMOS at home.
If we think ATMOS is a 100% waste of time and money, then, of course, we won't.
No right or wrong here. Just personal preference.
