I may switch away from Apple for the first time
I have owned a 3GS, 4, and now a 5. (I've owned Macs since the late 80s)
The 3GS was a great phone. I have no complaints.
The iPhone 4 was horrible with reception and keeping calls connected. It also had a hard time keeping WiFi signals in the same room other devices had no problem. Also, the lock button on the top and the Home button both broke after a little over a year.
I now have an iPhone 5. The lock button is completely broken. I have to use the little touch screen accessibility feature, which means I have this annoying graphic square floating over everything, now. Like the 4, it can't hold WiFi signals in rooms other devices can. I end up turning it off and using LTE in those rooms. The Hold button requires I press it 2-3 times before it works.
It's pretty obvious Steve Jobs is needed since the iOS 7 launch, because I'm pretty sure that garbage would not have gone out the door. The user interface is insane with the thin lined fonts and thin lines for buttons on top of pure white backgrounds. It's much harder to read, now. Apps seem to crash more often now too. It's not a huge deal because you just launch them again, quickly, but the quality control is not what Apple used to be. The voicemail system is buggy. When I listen to a voicemail up to my ear, my ear activates a button. It's not turning off the screen when I place it up to my head. Also, when I swipe the voicemail icon on my lock screen, it used to immediately play that voicemail and it would remember that I had it on speaker before. Not anymore. Even though the SPEAKER button is highlighted, it's going through the ear speaker. I have to press SPEAKER twice to get it to work. Speaking of highlights, the choice to have faint blue as a highlight makes it hard to recognize. Like I said, the user interface is horrible. Seriously, iOS 1.0 was much better in this regard. It just worked. Apple used to be about "it just works". Not anymore.
I'm really unhappy with the iPhone 5 experience. I like the form factor of the phone itself, but the OS and the quality control has me wanting to check out other options when my contract is up.

Why is it when people think "Curved Glass", they assume it's for the display, which would have incredibly limited utility. Why don't they think about the more obvious use ... for the windows on the back of the phone!
We already know that aluminum will act as a Faraday cage, blocking signals from getting out, and that's why Apple used those glass windows on the back of the iPhone 5/5S. If they want a rounded back on the device like some of their other devices, they'll still need to have glass windows to allow wireless signals to penetrate the device. Curved glass would be perfect for that.
Why don't they use what they used for the 3GS? It worked great.
