I own my SIII for 3 days. I'm a very demanding user, and I loved the S4 as the SIII too. One friend of mine, bought the S4 some weeks ago. I don't see huge differences and I can say (as always I whine cause others have a better phone than me, which mine is crap) BUT, man it's the first time I'm so happy with my phone even in comparisson with the S4. I play whatever demanding I want, I take cool and clear photos, I never had issues with the ram. If you have the money buy the S4 (or wait for the S5). Otherwise buy the SIII, it rocks, and it has a lot of roms and kernels that give the option to overclock not only the CPU but the GPU too (from the stock 400 up to 700Mhz giving nearly 50 fps in the benchmarks!).
Even if the S4 prices fall in some months after the rumored S5 is released, buying now the SIII won't dissapoint you for the next 1-2 years. Or it maybe last longer (I mean if it can cope with the "then new" games).
What you will miss from the SIII that SIV has (extra features that you play for the first week, then you never use them after it):
- IR remote (ok maybe it's handful sometimes)
- Glance sensor that pause the video after you turn your eyes from the device and it play it again after you look at the device
- One feature that you select links, scroll etc with out touching the screen (it really sucks lol)
- Temperature sensor
- Humidity sensor
- Gestures (wtf)
What you may really miss
- 2GB RAM (Consider that the sensors are memory hungry, so actually there is no such difference
- A better GPU
- LTE (depends the device version for your country)
So I would still prefer the SIII even if SIV has a better GPU. What? Oh the CPU? 8 cores? Really man? You wont see any difference,there is no actual practical use
(don't make me to say the same for the 4 quads too). The speed? Cmon, the first powerful cpu has 1,6 while the SIII has 1,4. Overclock it to 1,6 or 1,7 just to say you have a faster clock than the SIV.
SIII SIII SIII now! It's cheap, powerful and it will take the 4.4 Kit Kat version which is a way faster and lighter OS. Go for it!
