It appears to me that Microsoft is doing everything it can to self-destruct the Windows phone line. Recent releases are less than appealing, compared to other phone makers (IMO). Their share of the mobile marketplace continues to decline. I am most disappointed with the endless delays of Windows 10 for phones. December was the original time-frame given. It is now March and so far nothing. I want to see how 10 works on the Lumia 735 I have. At this point, I've given up on Windows for phones. I am keeping the 735, but I just replaced it with the new Galaxy S7 Edge. Back to Android I go for my secondary line. The 735 is a great little phone, but it cannot compare to the iPhone, Samsungs, LG's, etc. The Windows phone OS is missing too much compared to iOS and Android.
