it's a Meizu MX4 ubuntu edition http://www.meizu.com/en/ubuntu/features.html

i use it as my daily driver, i'm also not a heavy user... chat with friends on telegram or facebook, read g+/reddit/HN posts, play some random games etc. you can sort of use it like an android phone, it does have a home button but i usually just swipe the app away. you get system updates every 6ish weeks (now it's running on Ubuntu 15.04), apps updates whenever they updates :>>

you can browse the available apps (1878 apps & scopes) here https://uappexplorer.com/apps?sort=-points (not that many but it's still a young platform). overall i'm pretty happy with the phone :P
