Someone asked who make a $400-500 phone that is equal to the iPhone 5c?
My honest answer is no one that I know of this second but the Nokia 925 is about 95% as good and for a LOT of people, it is really better. IMHO it has a superior OS in terms of navigation at least, superior display, and superior camera then even the 5s. Apple still deserves an edge if price is a non issue since the iPhone has the better ecosystem even though Windows 8 mobile is really catching up quickly for the apps that most people use. And the Galaxy S3 deserves consideration as well. (It has a somewhat different set of advantages/disadvantages)
But if you simply asked that same question in 2-3 weeks, the clear answer will be Google/LG with the Nexus 5. I own Apple and Microsoft stock so I am biased towards both companies but even I have to admit the next Nexus will be a game changer. The Nexus 5 will probably be priced at $300-$350 and have a super fast quad core processor that compares to iPhone 5s, big battery, 16GB or 32 GB if you spend a bit more, 2GB or 3GB of internal RAM, a great camera with image stabilization that may be better then even the 5s and stock Android 4.4. And a great 5" display with very thin bezel. Google will probably have very small margins on this phone and that is why you can get so much for paying so relatively little.
I've owned Android phones, iPhones and Windows phones and am taking a mobile graduate school class on developing on all 3 platforms so I know about each of them fairly well.
My honest assessment Android manufactures other then Google with their Nexus line suck at supporting their OS in terms of upgrades so if your the type that wants to keep their phone a long time and upgrade the OS 2 or 3 times, avoid all Android manufacturers besides google. Quite honestly most high end Android phones have OS that most users will like but its still at least a minor black mark that its hard to upgrade unless you are a techie.
Besides my Android phone, I currently own a Nokia 521 which is an amazing value and shows the Windows Mobile 8 OS is absolutely great. From a purely OS perspective, it really has leap frogged both Android and IOS. If price is not a consideration, Windows 8 on the desktop is not as good as OS X right now -- I am typing this on a Macbook air but own an HP All in One with Windows 8 -- since it really needs the 8.1 update to fix a few things. That being said, live tiles work absolutely great on a cell phone. And unlike cheap Android phones, with Windows Mobile the OS runs smooth as butter on low end hardware like the Nokia 521.
The reason no $400-500 phone right now is clearly better then the iPhone 5c is other then Nokia, no manufacturer is really taking that market seriously. Phones in that price range are usually sold to somewhat gullible people on contract and increase the margins of the telecom companies such as Verizon, At&T etc.
Besides Google/Nexus, Nokia/Microsoft is the hope of the industry of bringing the margins on high end phones such as the Samsung S4 and iPhone 5c/5s to more reasonable levels.
Google/Nexus really do no advertising so there sales will always be somewhat limited. And quite frankly not that many people realize how good Windows Mobile actually is so the Nokia midrange phones probably don't sell as well as they should even though sales are increasing through word of mouth.
I've owned an iPhone as well and still have an iPod touch. If the 5c was priced at $450, I would have bought one but now I'm either going to get a Nokia 925 used, perhaps used iPhone 5 or Nexus 5 when it comes out.
(Not all of the Nokia phones are executed as well as they should but I've owned the 521 and its ridiculously impressive for the price and looked at the 925 enough to know that is very well executed as well).
