Re: Pareto analysis
I do use WinPhone, and can bear out your comment (at least for the default tiles - the size can be changed easily either larger or smaller on a few different set sizes).
The phone (a Nokia 640) is good for what it does - calls, SMS, WhatsApp, Slack plus the usual tools like the alarm clock, email, calendar etc, and has a battery life of between 2-4 days if I don't hammer it with excessive wifi etc.
In light of the articles comments, it's still a bit surprising that the OS didn't do better than it did, and indeed quite a shame as for at least the basics of being a phone it does work well. And for everything else, there's my Android tablet...
