That's somewhat a different definition than the comment I was replying to. There are plenty of people who may want to fly somewhere who aren't going to upgrade their phone to the latest and greatest every two years (which is what the comment above was implying: that since flying is supposedly a 'luxury' item it can be assumed that the customers have the latest and greatest phones).
