Yesterday, the most valuable company in the world (by market value) introduced their latest product. Leading up to the announcement of the new iPhone, the traditional media and blogosphere were rife with rumors, spanning the gamut from the new iPhone only being available on Sprint to very solid rumors that effectively got it right. Who cares?

The real question is whether or not it makes sense for you to buy one.

For me, the answer is easy: yes, it makes sense. The devices I use are never fast enough for all I try to do with them, and I am using my voice more and more to interact with my phone, so I am looking forward to having the new Siri assistant so that I can use my phone more consistently and safely without looking at it. With Siri, I will be able to hear and reply to text messages, compose emails, change meetings, and more by conversing with my phone. I'm looking forward to that.

Plus, my daughter had her iPhone 3G stolen this summer and has been waiting for a trickle-down iPhone since then.

For you? It may not be as clear.

Here are the criteria I would recommend you use to decide:

If you cannot purchase it with a contract, I'd consider waiting
If you do not make heavy use of smartphone features like email, web browsing, camera, and apps, the iPhone 4S is likely overkill for you
If you make heavy use of Internet data, the iPhone 4S will be a benefit, but only if you are an AT&T subscriber
If you're a heavy user of a camera and either want better quality on your phone or would like to leave your camera home most of the time, the iPhone 4S will be great for you

So, what do you think? Is the iPhone 4S in your future? Hit the comments or Facebook with your thoughts.

I'll let you know more about what I think after I have had an iPhone 4S for a few days.
