Hope you bought the S100 ... because the extra money is worth it.
The thing is, you want to consider the price of the camera amortized over the time you own the camera.
If you're thinking you're going to get a better camera or an additional camera that is an upgrade in a year or two, then no, just go with the lowest priced camera.
However, if you are going to be using this camera as you main camera for 3-5 years, then think about the cost of the camera more in terms of an investment you are making in the enjoyment of taking photos and the quality you get in your photos.
Given the how much better your photos are going look ... and the various wonderful features you are going to get with the S100, you have to consider the extra money more as an investment that will pay itself off over all the years you are going to use this camera.
Two years from now, you won't have to look at other people with better cameras with feelings of jealousy. You'll have a top, top camera in 2, 3 even 4 years from now.
