Can't agree enough... And aside from the early bugs and marketing blunders it's one of those 'how can this product possibly have failed?'.
Such a great product and people never knew why they should buy it over what is basically a shitty simple app launcher with separately siloed apps, email and files. (I'm pointing at both android and iPhone, neither is as productive as a BB10). People have just settled for what apple have told them a smartphone is.
And one more thing... As Andrew points out, the gestures could be confusing to a new user but I didn't hear one shiny shiny gadget reviewer complain when ios got a whole load of gestures.
Oh, and thinking of gadget reviewers, read the verge review of the passport to find out why most tech journos are lazy, ignorant and contributed greatly to the reason why there is now simply a smartphone duopoly. //rant over//
Ps I also fully admit that BlackBerry seem to have done as much as possible to sabotage themselves
