I guess the 4s was aimed at people like me... I picked one up yesterday morning and up to now I love it!
I had a 3gs which I loved, but newer apps coming out need more CPU power and were running a bit slow on it and honestly the camera was simply awful. I did not get a 4 as I had only had my 3gs a year when the 4 came out, plus I generally never buy the first generation of anything.
I have to admit that the quality of the camera on the 4s really surprised me. It's obviously just a phone-cam, but it blows the 3gs cam out of the water!
The cell phone radio/antenna in the 4s is also quite an improvement over the 3gs, I get 1-2 bar reception in areas where my 3gs (and previous blackberry) got nothing. Battery life also blows my 3gs out of the water.
A few quickie pics I took this afternoon with the 4s:
