Well Xiaomi's Business Model worth something to talk about.
Owners of MI2S, which was just announced as Flagship at April 2013. Could not use Miband.
MIUI V6 for MI2s - Would be based on android 4.1.xx. rather then KitKat 4.4.xx.
I can understand if I would not be able to use the Phone Unlock function. (No NFC in MI2S). But why not to have MIUI based on 4.4.xx and to be able to use MiBand with low battery consumption by BT.
This reminds me that MI2S hardware, could support RAW file photography. But Xiaomi did not let us use it. They even blocked the Mi2raw app. in MIUI.
So is this your Business Model ?
Why not to use the Google way. "Don't be Evil"
dear Hugo is it familiar to you?
