I'm 20 and my first smartphone was and still is the Lumia 820.
I live in Romania and so for a few years, the dominant force was Symbian and everything Nokia. I didn't really care for smartphones when I was younger.
I first heard of Symbian and Android when I was in the sixth or seventh grade. By 2010, smartphones were all the rage, yet I still knew almost nothing about either platforms. I knew iPhones were cool and expensive, Android was something ... Other than iPhones, Blackberry was something that I saw every business man using and made very little sense to me and Windows Mobile (I learned about it only when it got to version 6.0) was overly complicated, but looking cool as well (the Vista inspired Start).
Anyway, I still didn't care for the smartphone phenomena as I was more than happy in 2008-2009 with a Nokia 6500 slide. But at least now I had some idea about what was happening in the teach world. In 2012, january-march or so, the marketing exploded about something new called Windows Phone. There were ads everywhere, on TV, in Shops, ads on the internet about the Lumia 900.
My god, what a wonderful piece of tech. I was completely captivated. I was in desperate need of having it. Yet my family deemed it to expensive to warrant it's worth. Buying one with a data plan was even more absurd. So I mostly used cheap feature phones. A Nokia 5130 XpressMusic the most.
Last year I finished high school and got into college. My parents were a little more generous and said I could get anything I wanted. By that time I was drooling over the Lumia 720 but in the end I put better specs first so in September 2013 I got the Lumia 820 unlocked for 465$. Not the best deal ever, since there were stores selling it for as low as 310$. Oh well.
It goes without saying that I am completely in love with this phone and I am gladly recommending Windows Phone to anyone I know ever since.
