I will show off face unlock, the amazing browser with quick controls, social hangouts, 4G LTE, and the overall system look.
Also, people, the reason you didn't get a high end phone when you were 15 is because we didn't have Galaxy Nexus devices back then, silly. A flip phone was pretty much the hot thing even 6 years ago, let alone before that.
As time goes on, the people in this country have a higher standard of living. Another reason why "kids these days" get more than kids in the past.
If you wouldn't have said you are 15, I would have never known. You write better than 90% of the "adults" in these forums. In fact, I would say (as a 22 year old) that you don't mention your age from now on. In forums like these, it only makes people react to you in a completely different way, and you sound like the kind of person that likes to be treated as an adult.
