RE: what 2.4 article
Back on topic...
Don't worry guys, 2.4 is here to stay. It has issues, but they are minor - Extremely minor, compared to 72MHz. But simply because it is not perfect (nothing is), some people prefer to stand on the sidelines and complain rather than (shudder) spend money on a new radio, or worse (major shudder) learn to do something differently.
If some people prefer to stick with last century's technology, that is their prerogative. They will be viewed in the future right along with those who told early auto owners to "Get a horse".
