The iPhone 5 is not merely a bigger screen and a new connector. Even with just those two new things, it's a BETTER screen than the previous (which was already the BEST) and a FASTER connector.
iPhone 5's display is even better than before. The processor is second to none and beats the hell out of Samsung's Exynos. Camera is better. Speakers are better. More microphones, better microphones. Thinner design, better build quality, better materials. Let's not forget about software. Samsung put their POS UI layer on Android. And a bunch of half baked features that don't really do anything apart from being a spec sheet filler. Not to mention they hardly ever work.
If one were to prefer Android, I'd recommend something from HTC or the Nexus line. Even Motorola. All Samsung does is bash the iPhone. But the funny part is that they are currently under the iPhone's foot. Their ads are hilarious. It's a sight to see that a company is bragging so much about some crap they found in some random gutter in a 5th world country. I almost feel sorry for them. Ignorance is bliss.
Ignorance is bliss, indeed. This post proves that.
