I agree with what you're saying for the most part except the last sentence. The two 1800e boxes I bought over the past couple months had 5.1 already installed on them. And I think the older models deserve the full right to completely function on 5.1. I personally prefer 1800e over 1900ac because it has the full size sd card slot, specs are minimally different, and it's cheaper. The biggest thing I can't get is how long these things take to fix. And whenever there's a new firmware release that's better than the last it's like a huge breakthrough for mygica. Maybe I don't know enough about the technology, but I think it should really just take weeks to correct issues like this at the most, not months and months. But I agree these boxes should be fully functional to standard upon their purchase.
I don't mean to be overly negative about mygica, but I do feel you guys can do things a lot better. Lots of room for improvement. Constructive criticism.
