I’m curious because, at least for me, the loss of the headphone jack is a big deal-breaker. I think my next smartphone will an an Ubuntu phone. The headphone jack is a very important piece of technology due to its ubiquity, flexibility, and ease of use. Price is also a benefit of the headphone jack; you can get a pair of 3.5mm headphones that sound good enough for $30, while the same is not true with Lighting and Bluetooth headphones due to the need for built-in DACs and amplifiers. The headphone jack, is the main reason for me wanting to switch to Ubuntu phone. The other reason is the functionality. An Ubuntu phone is much more like having a computer in your pocket, without the limitations Apple puts on iOS devices. Also, having Terminal on my phone would be very useful for work because in my line of work, it can be very useful to be able to use things like SSH, ping, and traceroute, which is something you can’t do on an iPhone. I won't switch immediately. I’m just thinking about switching in a couple years if the iPhone 7S and the iPhone 8 don’t have a headphone jack. Who else is thinking about leaving the iPhone? If you’re going to leave the iPhone, which phone operating system would you choose, and why?
