So it's not just hard, but impossible.
Around half of all smartphones sold today run Android. I don't think there are that many 18 year olds.
Your phone should update with the latest features as soon as they are available not a year down the line.
Yes, it should. But most users don't really care, as long as it makes calls and can get on Facebook and run Angry Birds. Apple/MS fanboys are correct that Android geeks aren't representative. But neither are they.
It's like playing roulette when buying a phone trying to find out which OEM will update there OS on time and which will not.
GSM Nexus.
Very non technical users freak out if they switch something on one day and it's all different.
It's probably the 18-20 demographic who cares about having the latest versions.
