IMO another thing that folks fail to contemplate is this: variable rates work 70% (caveat: I don't know what the true percentage is, whether 60%, 70% or 95%. The important point is that it's not 100%) of the time. They don't contemplate that, what if now is the very few times that fixed is better?
It's like Anchorman: 70% of the time variable beat fixed, everytime.
