BlackBerry has just reported a $935 million hit in Q2 due entirely to what it's calling a "Z10 Inventory Charge" -- in other words, a charge against inventory and supply commitments for a flagship handset that is failing to sell. Echoing Microsoft's catastrophic write-down due to unsold Surface RT inventory, this single loss was enough to wipe out much of the company's quarterly revenue of $1.6 billion. When added to a further loss due to corporate restructuring, it resulted in a final GAAP loss for BlackBerry of $965 million.

The Z10 wasn't a bad phone, scratch that it isn't a bad phone.
It just needed more consumer mindshare in my humble opinion.

This means bad news. The third place runner has fallen. Nokia too.
Basically the state of the smartphone market is a duopoly between Samsung and Apple. Samsung has the larger marketshare, Apple has the larger profits. Both have equal influence on the market and each other.

Not the same. Blackberry is obviously trying to manipulate stock prices because they want to go private. They're very much interested in manipulating the news to make it look much worse than it really is.

that z10 has too big bezel. they deserve failfure at first glance

No they don't. No one "deserves" failure. You're just being facetious.

I assume he was being sarastic. If not, I'll pray for him.

It has been duopoly ever since 2011 when Symbian was officially given its head shot after sliding down in Western markets from Android already. WP is the only one growing with Android at the moment and will likely achieve that 10% market share, but not much further than that.

Blackberry as what it was is dead and will be sold for parts by the consortium. It's a dead end as was WebOS or MeeGo without nearly enough funding to create actual viable ecosystem for the size of the company in such a fierce market.

BBM and patents (how valuable they are will be seen, when Motorola's much more impressive patent holdings have not been worth even near what Google paid for them) might be the new core for the "old" company, like NSN, HERE and Advanced technologies are for the new Nokia.

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.

BlackBerry's epitaph should read:

"Oh yeah, maybe we should get some developers"

And the price? Here in Brazil, Z10 costs more than $ 1,000
S4 costs half!
