My reasons why I bought this Lumia:
1. I want to try a Windows Phone
2. Cameras with LED flash at the back (Both back and front. But I'm still disappointed that Amber ruined its image processing and Black didn't resolve this problem.)
3. ClearBlack display and Glance screen
4. 2x HAAC mics
5. Here Drive+
6. NFC (Even though I don't use this, it's such a nice feature!)
7. Backlighted Back, Windows, and Bing keys
8. Lumia 720 is a little bit high (in price)
9. Lumia 520 lacks some features
10. I thought Lumias 625 and 630 will be a "better and advanced 620" but it's not!
And lastly, I like how the Lime Green looks like. It's still better than the "Asha" Green (501, 625, Nokia Xs).
