I'm like some posters, just a few times I wonder what its like to to go back to Android, the LG G3 and HTC One M9 are very intriguing, but then I snap back to reality and realize I really hate Android's cluttered interface and the whole reason my family is on Windows (4!) and I've own two myself including my 1520. My consolation for some apps is that I have a work phone on Android and if I see the occasional tool app I am missing I just load it there, but I find I don't use them that much either. 1520 is fast, smooth, great battery life, nice screen to watch Netflix. As far as the camera AND its 4 mics recording video at 4K?, wow! I recently recorded a Choral performance in a cathedral, where they sung Boroque and Sacred Music pieces, and the quality was superb, like a studio quality recording when played back on a Hi Fi stereo, you will be hard pressed to find a phone that can do that right now. 1520 and Denim delivers!
