That's a fair assessment, I think my opinion changed in the process of writing it! To be fair though, I'm really saying that there isn't a source of such information, but even if there were, it might not much matter for most, myself included. If I don't regret not 'upgrading' after the fact, when I do have slightly better information, I probably wouldn't think it was worth it in advance either, even with perfect information.
