For me the thing that stops me fully committing to #ubuntutouch from ubports is #OpenStore There are no official apps, ie no official Instagram / Facebook / Twitter apps.
If you want to be the alternative to iOS and Android you need to learn the lessons from the failures that went before. Windows Phone being a prime example. By the time they got official apps from Instagram / Twitter / Facebook etc it was too late people had moved on tired of waiting.
Until official apps hit the Ubuntu Touch platform it will be just a hobby for me and not a daily driver.
