I shake my head at this attitude. It makes me wonder if people know anything about technology.
The 4S and the 4 don't share any DNA. They are completely different phones. The 4S has a completely different chip architechture, GPU, SPU, etc.
The 4 and 3GS share the same chip architechture, have the exact same GPU, SPU, etc.
Let me put it this way: If you have two laptops, and both have Intel Pentium 4 chips in them, but one has a different case design, are they different laptops? If the insides are the same, then no.
But if you have two laptops with the same case, one has a P4 and the other cas an intel Core i7, are they the same? The case is the same, so they must be the same right?
They arent the same. Even a little bit.
The 4S is a MASSIVE uprade. 3-4X bigger then the 3GS to 4 upgrade. At least.
You keep telling yourself that. Apple's 'magical' ads must have gotten to you.
I own both phones, and the AVERAGE consumer most likely wouldn't even be able to tell which one is which if they were both sitting on a table and they had a few minutes to play around with them.
