[citation][nom]pacomac[/nom]To me the S4 looks just like the S3, but I'm not going to take the piss out of you because of this. I guess Samsung like Apple have finally stumbled on a form factor that works for them and suck to it. Many iPhone customers don't want a drastic change in design as some will argue its the best looking phone on the market. A new CPU and GPU is a big deal in the world of Apple. Keeping ahead of devices with double the ram and 50% higher clock speeds in the Open GL benchmarks is really what Apple does best. Their CPU's are simply better than the opposition at the same clock speed.[/citation]Pfft. My Galaxy Tab 2 7.0 can give an iPad (3? Retina? whatever) a run for it's money in speed and responsiveness. I'll agree with you on the OpenGL though, Apple's kit is undeniably rather nippy in the graphics department. If I played games on my tablet I'd probably care or something. As it is, games seem to run great on this old thing anyway.
As for the CPU... you do realise their design is not dissimilar to every other ARM-based phone on the market? Albeit with a bit of rummaging around to change some things (which most high-end SoC developers do these days) there really isn't much to differentiate them. If there are tangible performance differences where the processors are concerned, they would be primarily due to software.
