Realistically, I don't think any year will be the year when Linux for mobile takes off, ironically for the same reason why Windows Phone failed, and that is app availability, or the "will my banking app work on it?" problem.

We really can't find a sincere friendly OS like Linux. I wish Linux and other friendly phone systems had more hardware support. Android is dominating with its "I'm the ruler" philosophy, bc Google knows the alternatives are limited.
