Yeah, because Blackberry has no touch interface comparable to iOS. People don't want what RIM is currently offering, but they do want something like you see in this video.Whilst 10% might be accurate in terms of total handsets sold over the years including legacy ones floating around it certainly isn't accurate in terms of quarter to quarter shares. According to IDC Blackberry accounted for less than 5% of smartphone handsets shipped last quarter and this is still in decline.

When this comes out, Blackberry will stop its decline and then start to peck away at Windows Phone. You can't just say RIM will fail, because RIM isn't even in the game yet, but it will be, when Blackberry 10 comes out.
People out there are DYING for an open source alternative to Android. This one is backed by the Linux foundation so when it comes out, you'll see it steal Android users, bit by bit, slowly but surely.Tizen doesn't yet have a product and Meego/Moblin/Maemo haven't done anything to this point so there is no reason to believe a frankenstein-like mashup of them will do much in smartphones either.
Oh yes, it does exist. It's called the "people who don't trust Google or Apple or Microsoft" market. This OS will definitely grab some people away from Android as well as people who are currently too paranoid to buy a smartphone because of the corporations involved.Firefox OS currently seems like nothing more than research or some academic project. It's a non-product looking for a market which I don't think exists.
I'd argue that there hasn't really been any competition to begin with. Windows Phone is the only real competitor and that phone's interface doesn't even seem like a good alternative to most people. Once all the OS's you see in my poll reach the market, you'll see that 85% start to move around, along with the other 15%.Don't get me wrong, the more players the healthier the system but with iOS and Android accounting for 85% of smartphone shipped last quarter it just seems like too strong a duopoly to break.
