I am looking forward to your OS on all levels, although i think in a strategic matter that you should make a Senior mode for your phone, the senior market is death, lead by Doro, which is based on old Nokia platforms. Old people are to overwelmed by the smartphone capabilities and hate the Doro slow non-functional menu system, making a middle way inbetween its the way to go, by making a UI which is easy and simple for senior based upon you age, you would have the possebility to overtake the entire Doro market.
Just making this point because the older population are increasing, of course knowing that the population will be more IT literate in 10 years, compared to now.
The lifespand of your phone OS following your age, can also start with kids, giving them more possebilities of evolvement over the course of time having the phone, with access to more complex possebilities the IT brighter they get.
Please consider a Simple UI for Seniors, as the phone market needs expansion on that level too.
