march 22 2018 1 year anniversary. www.reddit.com/r/AndroidTV/comments/869va7/happy_1_year_anniversary_to_mibox_nougat_70_beta/ i don't regret my purchase at all and i'm not even sure the update to 7 or even 8 will really change anything other than the fact they said i would get something and i still haven't gotten it. my only complaint about the mibox is storage related. i'd like to be able to install more apps on it without juggling what's on it. (although a good bit of the apps on it i barely use).
april 30 2018 oreo beta starts getting pushed to beta testers. www.reddit.com/r/AndroidTV/comments/8g73yl/mi_box_oreo_update/
june 22 2018 15 months since nougat beta. hopefully i don't see you at the 18 month anniversary.
I gave up and bought a shield. Totally worth it for me. The Mibox always had little issues that annoyed me, and the fact they promised Nougat by the end of the first quarter 2017 pisses me off. Defintely tainted my view of the company and would be vary wary buying from them again.
