VPI, I'm curious how you will like the S100 over the long term. The improved high ISO performance is definitely a boon, but I've been wondering if the 24mm equivalent FoV is actually a detriment. Tiny sensor cameras like the S95/100 already suffer massive perspective distortion at the wide end. When using the S95 and its 28mm FoV equivalent, I find it takes considerable care to avoid getting the surreal cartoony look of such a wide field of view on in a tiny format.
Of course it's possible to zoom in the S100, but there are two caveats to that: First, it's important to remember than tiny digicams don't freely move throughout their zoom range, they have different "stops" along the way. I'm not sure where the first stop is after the 24mm equiv. wide end. Secondly, the aperture of the lens get smaller as it zooms in. I don't have the numbers in front of me, but I suspect the first zoom stop is smaller than the F/2 of the wide end. Beside the control dial, the the F/2 glass on the S90/95/100 is the main attraction for me.
Of course, all of the above may be largely irrelevant in real world use. I have no doubt both cameras can produce great results in skilled hands. After nearly seven years of shooting digital, I found I dislike super wide angles most of the time. I'd love an S100-like camera that offers the equivalent of 35mm FoV at F/2. Oh, wait. I just described the Fuji x100.
36 fricken megapixels? EWW. Have Nikon learned nothing? Even Canon is backing off on the megapixel war. How about a D3s's photon-inhaling sensor in a body that costs less than $5000? The arrival of the D800 makes the likelihood of a 'D700s' seem pretty remote.
