coming from an iphone4. i wanted to get an iphone 5. but the hardware is meh. i just heavily dislike the design.
multiple issues, the back of the phone is made of at least 6 different pieces, different materials. which makes it less strong. then they used a weaker metal too. so the aluminum i have seen reports of people's phones bending at the volume buttons. it just shouldn't happen, it's flat out poor design, which is inexcusable for apple. they could have easily used slightly thicker aluminum to fix the bend issue, this means they didn't test the phone long enough. just watch the iphone 5s is going to have a thicker aluminum band around the phone. in fact, i think some of the newer models are coming with a slightly different bezel. probably to help against bending.
i don't like the new taller aspect ratio.
i actually liked the new maps on iphone 4, the design of the text and vectors made loading and stuff really fast.
the design though is what really killed it for me. and theres only one iphone 5 design to choose. it's either their way or the highway. so really if they don't do the design perfectly how i like it, theres no other option but to go with it, or get a different phone. so i might as well jump on some other ecosystem now. i don't really like android. but the hardware issue is fixed there. i could go to multiple different hardware vendors and find hardware that i like... same with windows phone, but the os design is very cool. so i went to windows phone.
i picked up my windows phone so far so good. lumia 920. i like the curved glass, makes it a little heavier, but it's oh so solid feeling. no flex to this glass screen. also i love the solid polycarbonate body. and windows phone 8 is fresh and cool. i like green tiles
