I originally got the lumia 920 sim-free after being very excited about it after reading about it. I returned in within a week due to a few things that really annoyed me about it - at least, annoyed me enough to go back to my iphone 5 that was gathering dust:
1) The IPS display - reviewers loved it but I prefer amoled, and I ESPECIALLY prefer amoled on lumia phones. I had a lumia 800, and the amoled made the tiles so vibrant and the blacks perfectly black. You just don't get that with IPS.
2) The weight. There are a lot of wannabe alpha-males types lol on the forum who say the 920 wasn't THAT heavy, but to be honest, in a suit-trouser pocket, it IS. Not only that but 4.5inch is (nowadays) a middle-range screen size so to have something with that size screen but weighing more than a galaxy note 2 was annoying.
3) This is pure OCD, but aesthetically it always annoyed me why on the 920 there is this random large space between the capacitive buttons and the bottom of the handset. Just looks really odd.
..Anyway, long-story short, clearly my soul-mate must work at Nokia because now they're releasing the 925 that not only weighs less, not only has an AMOLED screen but also has almost entirely got rid of that wasted real estate. Bottom line, I'm extremely excited - 925 MIGHT just be the best phone I've ever owned (no haters, but that crown is still with the iPhone 5).
As I said in other post, being a hardcore superman fan since the chris reeve era, the 14th is shaping up to be something of an early christmas day
ps. they've also included a white balance/saturation slider so you can customize the amoled colour vibrancy which some have differing tastes too. Perfect.
