Pretty much sums up their problems, and the reason why they're pulling out of the consumer market in favour of chasing enterprise users instead. They chased consumers with sub-par offerings for so long, and promised big, but delivered small with BB10. To add to the problems, consumers don't generally care about Blackberry's biggest (and arguably only) advantage, security. But some businesses do care, and others can be tricked into caring.
Bb10 delivered and was no more buggy than any new OS, the failure is mind share and perception, simply put it's a lack of belief in their product and most negatives I've heard are from people who've never used the product. I had 1 person tell me how horrible Bberry was while playing with my phone and going yours is pretty cool, who makes it. I said that's the new Bberry z10 , the first bb10 device, he goes this doesn't look like a blackberry I didn't even know they had new phones.
This is a true story, people still think of the old bberries and honestly if they were as buggy as many claim, then they wouldn't be highly secure.
