I had to make the choice between iOS/Android after too many apps and services I rely on for both work and personal use were either dropping WM10 support, had dropped or had no support. Shame because last three phones have been WM. I needed access to Microsoft services due to work. Anyhow, looking at options from both iOS and Android ended up buying Samsung Note8. It was so easy to setup my existing MS services. I use Outlook, OneDrive, etc.. Even have various email accounts setup under Outlook where I can manage them easily. I'm sure it would have been easy under iOS too, but for the same pricepoint of a plan for the Note8, I would have only got an iPhone 8 256GB (in Australia). Now having a device that is actually supported by developers means I have a full featured banking app - sadly missing previously. I never really used Cortana much, however I've since found the Google Assistant MUCH faster and also ALWAYS understands my Aussie accent too.
