I wanted the 3Gs, but I left before it was released, so I ended up getting another 3g. After seeing how the 3.0 update really didn't meet all of the hype, I then looked at the other features of the 3Gs. I rarely took pictures with my iPhone. I use a Canon DSLR for that. The video would have been a decent addition, but I jailbroke for video before, and I really didn't use it much.
If I had purchased the device, I probably would not have thought about it much. Since I did not purchase it, and had time to think about it after the release, I figured that I wasn't missing much. Next year I will be getting the new version of the iPhone though. One that I would expect to have a different body and more features that are not common to other cell phones anyway (MMS, video, cut and paste).
They caught up with everyone else on basic features. Now they can focus on real upgrades.
