Ouch. As an BlackBerry Z10 owner, I can honestly say that I enjoy the phone and it's more like the Canadian take on Harmattan than anything else. There's plenty of flaws, but it fits my workflow closer than Android or iOS - but not as well as the N9. But it's darn close.

Folks will point at many factors - but overall it wasn't marketing. BB10 was just too late to the market with very little 3rd party support. They embraced the developers, there's more SDK's to make your work shine on BB10 than most any other platform and yet... here they are.

Just... wow. That's a lot of money to absorb.
