Actually, they <i>did</i>.  Manage to make me happy, that is.  I was very satisfied with Windows Phone 8 and 8.1 on my 920 and I&#x27;ve only had my 950 for a couple months.<p>Significantly, I&#x27;ve looked at iOS and Android devices during the same time and saw no appeal.  Android seems about the same as it was when I stopped using it, even though it&#x27;s been through several major updates.<p>So yes, I do hope they improve Windows 10 mobile, and dramatically so.  But I&#x27;ve only had this particular device for a couple months.  For me personally, this is the first time I feel partly disappointed with a Windows phone.  So I feel it is reasonable to be cautiously optimistic that they can improve matters and restore my happiness with the platform.
