My point is that there are generally two kinds of people around: people like you who buy something that works and keep using it until it breaks, and people like me who pray at the altar of new technology and like to have the latest gadgets as soon as possible.

I, for one, think the new 2.4 GHz radio systems are a worthwhile investment because even if they save one model from being shot down by someone turning on a transmitter on my channel while I flying, the cost will have been worth it. Accidents do happen, even to the most careful people.
