Welcome. But why did you feel the need to say that you're not a big fan of this section of the forum? Are your iPhone buddies giving you grief?
So what are some of the things that you like about the 925? There are many of us who dipped our toe in the WP8 waters with a 520 and are interested in what to get next.
I'm not a fan of this section for the same reason I don't like Samsung / Google fanatics to storm every iPhone thread of the forum. On this forum I like to speak about my Apple devices, while I speak about WP and Android on other forums (as you can see on my signature, I have pretty much all the mobile world covered).
BTW on Lumia 925 I found every things I liked about the 520, improved.
Construction quality is far better: the 520 was ok, but this is on another level.
Not so many differences running UI and apps, since the 520 was quite snappy and WP 8 a well designed os, but the better SoC and 1 Gb of ram are welcomed in more demanding apps.
The display is gorgeous while the 520's was average at best.
Camera is very good indeed, not at the level of the Icon/1520 (not to speak about 1020), but better than most of the camera you could find on the market, and with OIS.
At the street price you can find it today (around 250 here) the 925 is a very good device.
