I have an iPhone 5, iPhone 4s and an older Android HTC Inspire.  By far I find the Nokia 920 superior, for reasons not included above:

1.  Unlike Android and Blackberry, it has complete vertical integration, if fully integrating your phone to an entire system is important to you.
2.  Call quality is far superior to all the other aforementioned phones.
3.  Just as simple to use as an iPhone, but offers greater customization.
4.  Output volume far exceeds the others.  When using Apple navigation, I would often have to lift up the phone to my ear just to hear the voice prompts. Nokia is loud and clear.
5.  Re-sizing the fonts.  Since I need to use reading glasses, this can be problematic when receiving a text while driving.  Before driving, I enlarge the font size and can proceed safely. 
6.  Granted, it does not have a gadzillion apps like the iPhone; but let's face it, 99.99% of those apps are junk that no one will ever use anyways.  Nokia has all the apps one is most likely to use:  social networking, travel, tasks, world time, units converting, and music.  Granted that Apple has an app available for whatever special interest ANY person may want, whereas at this time Nokia is limited to having only apps that most people would want.
7.  I keep seeing side-by-side pictures by reviewers that show the Nokia camera looking bland next to the iPhone 5/4s. I find the pictures from the Nokia to be every bit as good as the iPhone's.  Perhaps these reviewers need to check their settings.   

The sunlight viewing of the screen is actually very good because they include a light polarizer in the screen (also in the Lumia 900), so while its a bright screen (I think it claims to be the brightest) the actual sunlight readability is achieved by the "clearblack" polarized glass.

A low  light picture would have been good to demo the camera though, as for me (and apparently a lot of other people) the low light capability clinches the deal.  For me most camera's are fine when there is plenty of light, but awful as soon as the light drops a little.

Connectivity 41%????
32 GB memory capacity!!
USB with file transferring!!
Bluetooth with file sharing!!!
Wireless charging!!!!
7 GB Skydrive!!
Do you want more? and in comparison with Iphone 5??? more expensive, less memory (16gb), no Bluetooth file transfer, no extra GB, no wireless charging.....
Are you an apple-fun or Android-fun boy?

"HTC's Windows Phone 8X is also much lighter with 130 grams despite the same screen diagonal"
The 8X has a 4.3 inch screen size, not 4.5 like the lumia 920. Also, the 920 is more than just a "decent" smartphone. It is certainly one of the best, and any normal person will be able to deal with the weight and size over time, if that even is a drawback.

@Amoin

Heavy does not mean a lower score. Not everyone thinks that a light phone is a positive thing you know. It could mean a sign of stingy manufacturing while a decently heavy smartphone gives a sign of more effort being put into it.

Weight Scores 100 ??? but you just said it's heavy !! :-\

The scoring for individual characteristics (weight, temperature, etc.) is calculated from the perspective of a notebook. High weight and temperature scores are thus not uncommon for our smartphone and tablet reviews.

Thanks for the article! I can agree with you that this is a good phone. No complaints from here. Go and get it if You haven't already!
