I went to my nearest AT&T store yesterday. Two things:
1. They had moved the WP display to the front of the store! It used to be towards the back, but they now had 4 models (one 920, one 1020, one 925 and one 1520) sitting at the first display you walk by when entering. At least they're making an effort.
2. The 1520 is a sweet phone. Like the 1020, pictures don't do it justice. It feels incredibly sleek, and even though it's large it felt great in my hand. For most things I could even use it one handed, even though I have by no means large hands. It feels thin, light and nimble, more so than the Galaxy Note 3 (though I like the Note 3's faux leather back, it's weird but kinda nice). It fit in my pocket fine, though sitting down with the phone in it could pose a problem...
Almost tempted to go back to AT&T just to get one... almost.
