If a phone works just fine for someone (and they can get a better deal on it now), why is it idiotic not to wait for the next one that is unknown just because it's newer? Perhaps they'll sell this phone off in a bit and get a newer one later, or perhaps they are more than fine having the currently latest one for the next 2 years because it works for them. Blindly going for whatever is the newest just because, now that could be referred to as idiotic on the other hand.
Yup. I love it when people call an idea or person idiotic because its something that isn't right for them. Like Mormonism. It's not right for me but I think it's pretty ingenious, not idiotic. Haha. Maybe that's not the best comparison but you get the gist.
