Just received the 1520.3 from B&H a few days ago; getting used to the size. :winktongue:
Wasn't sure I was going to keep it, but now think I will until something else comes along. Surprisingly, the performance isn't leaps and bounds above my dual-core Lumia 810. I think that speaks of two things, the speed of the OS and the speed of the internal storage of the 1520 vs. the slower SD card on my 810, where I kept most of my apps.
While I like it, I honestly think it's about 1/2" too big and just an ounce or so too heavy. This is the first time I've found that I'm taking careful note of the weight and size of a phone's case as it's now an additive comfort factor. Even though I have large hands (L-XL glove size), when using one handed the corners of the screen are just out of a comfortable thumb's reach and I have to shift the phone up & down. Something on order of the LG G3 (5.5") is about right for me as the maximum screen size & weight. Hopefully LG will take a crack at Windows Phone now that some of the hardware parameters have been simplified.
But otherwise the 1520.3 hits all the right notes: Glance, Qi charging, it's fast, great screen, great camera, works on T-Mobile, 32 GB + SD card (!). A lot to like there. :grin:
