I think the OS will mature rapidly in the coming year, thanks in large part to the apparent popularity of the 920, but it will probably be another year before it reaches the level of what the masses expect. And I really agree with the view that the use of the PureView label here was more a marketing ploy than anything else. Can one reasonably compare the cameras of the 920 and the 808? Based on the hardware specs, of course not, but Nokia itself begs the comparison given the fact that both are supposed to be "PureView" - i.e. something above and beyond in the camera department. Indeed, early indications were that the 920, although not comparable to the 808, would provide well above average photos, but those indications were dashed with Nokia's failure to follow-through at launch.
For me, the 808 really has all of my must haves, but lacks a number of the extras I get from Android whereas Android lacks a lot of what I really want and like (a good camera for one, a built-in FM transmitter for another, etc.). The 808 was my daily camera over the summer, mainly because I wanted to be able to take good pics and was willing to live without e.g. banking apps, Sirius radio and a few others I had on my SGS3. As the summer ended, I went back to my SGS3 thinking I wanted all it had to offer and that I would have less need for the camera. Of course, I used the camera more than expected and was pretty pleased with it (pics on the SGS3 screen always look stunning), but when I finally got around to transferring the photos to my computer and wide-screen TV, I was disappointed with what I saw. For me, the SGS2 takes better point-and-shoot photos than the SGS3, which itself excels with its HDR shots when you can get them to work, but both pail in comparison to the 808. Whereas a decent phone camera like the Samsung phones and iPhone can occasionally give you the "wow, the shots are pretty good considering its a phone", the 808 gives you the "wow, those shots are great for any camera" or "wow, I didn't even know that was possible".
Anyway, I had returned to using the 808 as my main smartphone, but still used the SGS3 as a surf/tab device at home. I really liked transferring the photos of the 808 to the SGS3 and viewing them on the high res screen. Then enter the 920. I was basically only hoping to get a new, true smartphone with a modern OS and a decent camera (by decent, I mean better than my SGS3) for regular daily use and I would continue to rely on the 808 for the really photo intensive days like get togethers and outings. I usually always await a review from GSMArena, but with this, I wanted to make sure I got the 920 before Xmas and jumped the gun. After I had signed up and while I was waiting for the phone to arive, a slew of reviews began coming out decrying the fuzzy outdoor photos. I nearly jumped ship, but a few days later, came the first promises of a fix. Then, the phone arived and before I even had a chance to unpack it, the GSMArena review came out with less than stellar marks for the camera. A few days later came a PhoneArena comparison to the iPhone5 and SGS3 cameras with worse than expected results for the 920. From what I've personally seen of the 920 since reflects those reviews findings. Agressive noise reduction and compression algorithms are causing splotches on all the photos. The pics in low light up to daylight was horrid. The pics in near complete darkness are, however, better than most others, but the same fuzziness and splotches are there too (although better a fuzzy, splotchy pic of a dark room that you can make some things out in than a black rectangle as provided by other phone cameras). Had this not been a "PureView" camera, this wouldn't be such a big deal, but since it is, and since early reviewers really gave the 920 good marks, I had hoped to at least have an improvement in the camera department. Hopefully this fix will give me that.
As to the OS, though, if the phone had delivered on the imaging promises it made, I would be more inclined to overlook some of the shortcomings. As it is, I'm more critical and less than impressed. My baseline requirements are a smartphone that handles numerous push email accounts flawlessly, offers Voip support in some sense (preferably SIP, but Skype would do), Word and PDF support including word counts in Word, good Internet radio options, banking app support and, last but not least (actually above all) a decent camera. All of these except the banking app support I have on the Nokia PureView 808. All of them but the decent camera I have on the SGS3. The 920 at present is missing functioning Voip support, word counts in Word, banking app support for my banks and, sadly, a decent camera. If this fix brings the 920's camera back into the PureView ballpark, I'm more than willing to stick with it for a while longer. Otherwise, I'm likely to return to my 808 and/or cross my fingers for a decent camera on the SGS4.
