My wife and I get all the functionality (and more) we want out of our recent iPhone 4 purchases, and with iOS 5, it will be improved GREATLY, so we won't be rushing out to buy the iPhone 4S, but after thinking it over a bit, I really don't understand what all the negativity is about.
The new 4S will process graphics up to 7x faster, and all other functions will be at least 2x faster. Even if the graphics were only 2x faster to match the other processes, you just got a 100% boost in performance! In all other tech areas, I consider that an upgrade, so why not in a phone everybody already loves? Add to that a camera that will now, more than likely, perform better than most point and shoot cameras AND record video in 1080p...
So it didn't change the look. Did it need to? I'm a huge fan of the iPhone 4 look, and I think it looks better than most of the phones on the market today. Heck, it *set the standard* that most others are cloning, and the 4S fixes the inherent antenna issue (allegedly, the phone isn't out just yet). Sure, I wouldn't mind a larger screen, but the graphics are already amazing, and as has been said before: It's not a tablet. THEN, it's now a world phone, and available on just about every carrier that people have been yammering for... Honestly, it seems like more of an upgrade than was the old 3G to 3GS back in the day, which people were thrilled over, yet now they yell "Crucify?"
I've messed with a lot of androids, too (my daughter even owns one of the latest and greatest), and yeah, a larger screen is nice sometimes, and they do seem a bit faster than my current iPhone 4 (not phenomenally, though) but the added bulk doesn't fit in a pocket or on my belt as well, and the UI... well, Apple got it right, the rest just don't "quite". Apple is still the lead dog in the cell phone pack, even though the gap is narrowing... (for the record, my daughter wishes she had gotten an iPhone, now)
All I'm left wanting is Flash, but I knew I wasn't getting that anyway.
There ya go, long rant. Apologies to the OP, but I had to pick one of the positive threads to say all o' that!
