Thought I would chime in concerning my 920/iPhone 5 experience thus far.
I have always been kinda anti-Apple. Just couldn't see myself as one of the countless iSheep out there and have always favored the dark horse if you will. My company pays for my phone, however the company only allows (and pays) for my phone if I use an iPhone. So instead of saving the money every month and just getting rid of my personal line, I kept my personal line, bought a 920, and now have a separate work line which is an iPhone 5. Every single one of my friends carry iPhones, they are the epitome of iSheep. They were very impressed with me not succumbing the power of Apple but also called me an idiot for paying for my personal line still when I could have just consolidated to one phone. However, to me carrying the 920 and sticking with the Windows OS is well worth the monthly access fee.
I will try to be as non-bias as possible here but some things have become blatantly clear in the first week or so. The first thing I noticed is the weight/form difference. The 920 feels incredible and I find myself just holding it and sliding it around in my hand even if I am not using it. I personally like the weight of it. I know a lot of people were crying because it was too heavy. but honestly it feels like a well built phone and for those of you it's too heavy for, well I suggest you hit the gym a few days a week. Sure the iPhone 5 is the lightest phone on the market but it's so light it just feels a bit on the cheap side. I often find myself just checking to see if I have it on me because it's just too light. As far as the actual form factor goes, it's a no brainer. The iPhone 5 just looks ridiculous. By just stretching the screen vertically it looks like my universal remote control. My friends (and others) defend that design decision saying that people want to be able to access the entire screen with just one hand. My rebuttal to that is first of all I can cover the whole screen with one hand on my 920 and my hands are probably on the small side. Second, I rarely use just one hand to manipulate my phone unless I am driving in which I really shouldn't be doing in the first place.
When it comes to the operating system, I get it., Apple's OS works and I understand that they want to stick with something that works.but it's just boring! They really haven't done anything too terribly different in six years now. I realize Windows has a long way to catch up to make everyone happy (we all know what a train wreck the Xbox Music syncing has been) yet we all know how refreshing the Windows 8 OS is overall as a whole. As far as the dreaded "app gap" goes, I can't honestly say there has been an app that my iPhone 5 has that my 920 doesn't have or something very similar. I will admit I am not a heavy app user so maybe this effects others more than it does me.
Before I start to ramble here, I will end it with this: When I have the phones sitting side by side at work or in public, not a single person has asked my about my iPhone 5. They instead ask me about my phone with the "huge and bright screen"
Cheers!
