Eh, no big deal to me. My Icon runs awesome on 8.1.1. I have no issues with BT connectivity to my hands-free devices, vehicles or my Band 2. Cortana works perfectly. I can make calls, text, browse the internet and anything else I need to do. 8.1.1 is just fine for now.
I realize some 8.1.1 apps may not get updated with the advance of W10, but maybe by the time that factor comes into play, MS will have W10m polished to the level of 8.1.1 and then I can upgrade through the Insider program or official OTA if it comes out.
Additionally, people this is just a phone. Sounds like some of you are so materialistic, you're missing out on Life.
