I'm so tired of seeing people post with the mindset that they HAVE to get the latest and greatest phone... like it's some sort of competition with other people. It's ridiculous. If you're constantly looking at getting the "next" model, then you'll never be happy with what you have. There will always be a "next" model coming soon. Learn to love what you have. Buy what works for you. Get out of the mindset of comparing yourself (or your phone) to others. That will just make you miserable.
I just bought a 1520 (red, ATT version) and I'm happy with my decision. I don't care that it's a year old. I don't care that it only has 16GB vs 32GB - I can add an SD card anyway. I don't care that it doesn't have QI charging. What it does have is a warranty that the 1520.3/RM938 doesn't have in the USA. Getting warranty coverage for it is more important to me than bragging about having QI charging. Maybe others would prefer the QI charging over the warranty, and that's ok - as long as that's what THEY want and they're not buying that model for stupid bragging rights.
As I said, if you're always looking for something "better", you'll never enjoy what you have. Enjoy the 1520 for what it is and how it meets your needs. Leave the bragging rights to Apple sheep.
