It is a perfectly justifiable, reasonable, and logical interpretation of the rules. Your point merely boils down to the fact that it disagrees with the FAQ. Now if Skip Williams wrote the FAQ entry in question, then I would agree that intent is just as he wrote it (in the FAQ). But if that is the case then metamagic rods are imprecisely worded, as a literal interpretation of them leads to Hypersmurf's position.
No, I made several points.
1) It disagrees with the FAQ (which btw, I could care less about).
2) It is an unclear position due to there not being any rules for it. And unclear interpretations should be avoided if possible.
3) The following sentence is totally unnecessary in a "preparation time" interpretation:
All the rods described here are use-activated (but casting spells in a threatened area still draws an attack of opportunity).
It seems likely that the only reason this sentence is there is to indicate that the rod is used spontaneously. It does not do a good job of conveying that information, but that appears to be what this sentence is all about.
There are two reasons why this sentence appears to indicate at casting time over at preparation time:
1) Use-activated items which effect spell casting are almost exclusively used when a spell is cast (in fact, I cannot think of one which is also used at preparation except ability score modifying items and a Ring of Wizardry).
2) The word casting in the sentence appears to be referring to the phrase use-activated.
When this sentence is combined with every other statement by WotC, it is clear that designer intent is spontaneous. And since these items are worded so poorly, it makes sense for the FAQ to add a clarification here.
If it is supposed to mean spontaneous, it doesn't do a good job.
If it is supposed to mean during preparation, it does an even worse job due to the issues of how to adjudicate multiple days of prep (or not) and due to the implication that the item has to be used both at preparation time and at casting time.
So, it is perfectly reasonable for this to actually be a clarification within the FAQ.
What is funny is that people bitch when the FAQ does a lousy job and then they turn around and bitch when it does a good job. This is a good job because a) it appears to be original designer intent, and b) the during preparation results in addition different adjudication from different DMs.
