The only real limitation you bring up is not being able to take a photo (I'd add reading email as well, not just texts). But there's no reason Siri has to maintain its current capabilities.
Have you read reviews of people struggling with limitations? Also, Siri offers a list of suggested tasks it can perform from the iPhone itself, based on the videos I've seen.
"Siri, on the other hand, feels limitless. It’s fuzzy, and fuzzy on purpose. There’s no way to tell what will work and what won’t. You must explore. I found it extremely fun to explore Siri — primarily because so many of the things I tried actually worked." -Daring Fireball
Even if Gruber is an Apple fanboy, I would suspect people to react more like him than you.
