Well, as far as Windows Phone hardware specifications go the 1520 will be in good shape for a long while. I mean, most of the WP phones in use today are running 512MB-1GB RAM, and single/dual core CPUs. I mean, I would venture to say that the 920/925 has a huge install base and you are looking at 1GB RAM and a dual-core Qualcomm S4 SoC running at 1.5Ghz. And, not to forget the 520. It is getting upgraded to WP 8.1. It's running 512MB and a 1Ghz CPU. So, I wouldn't worry so much about specifications.
