Hey, how are all you guys doing with your new toys? :) I just got back from my local Apple store with a 32GB model.
I have to say, I'm enjoying the 3G to 3GS upgrade much more than I ever enjoyed the 2G to 3G upgrade. First of all, the new iPhone is a LOT faster doing pretty much everything, they're not kidding about that. I knew things would be a little peppier, but I was amazed at how fast all my stuff synced over, and how much smoother the entire phone software is. If you've ever used the iPhone simulator and noticed that animations were much more fluid than those on the actual hardware, that's what the iPhone 3GS is like now.
The oleophobic screen stays pretty clean, and it also feels much nicer on your finger.
Voice control works, seems like kind of a gimmick if you ask me, but I've never really felt a need for it either.
The camera is really nice. Macro mode is something that I've wanted for a long time, and to finally get it is great. The video camera is pretty high quality compared to other cell phones, I'd say just shy of FlipVideo level, perhaps equal to FV in good conditions, which is more than enough IMHO. In poor light conditions, the framerate drops to about 15fps, and occasionally the video will stutter as the phone does something else in the background. If you're outside on a sunny day, video is amazingly fluid and very high quality. If you're indoors and lighting is good, you'll probably be satisfied with the results as well save some occasional hiccups. Low light performance is great for a cell phone camera, don't get me wrong, but don't expect dedicated camcorder level results.
So, how are you guys faring? Any other 3G to 3GS upgraders? 2G upgraders? Dare I ask, newbies to the iphone scene? ;)
EDIT: updated the camera section a bit
