Living with focused inbox...

The first few days I kept "losing" mail because i was on the wrong tab - was kind of surprised because I love it on my phone & web- but after using it for a day or so, I got used to checking both tabs on my desktop.  After weeks of use (I'm using insider builds), I like it. It does a good job of seperating mail that needs my attention immediately from not urgent mail. 

Unread count doesn't bother me - i pretty much ignore it anyway as I don't mark messages read automatcally and use Unread to mean 'needs worked or deleted'. (Which i clearly don't do often enough as i have 1000+ unread. :( ) 

I see many, many complaints from users in the comments on my website - at this point, I'd say most people don't like it - at least, not when its turned on by default. (but if it wasn't on by default, they also wouldn't know it existed).  Most of the complainers are using Outlook.com, if that matters (where it currently only works in outlook on the web, not desktop).
