Blackberry's lack of ecosystem

When Mark Shuttleworth announced the new Ubuntu phone I must admit that I was pleasantly surprised.  Many within the Linux community seem to feel uncomfortable that Ubuntu is attempting to become a mainstream operating system, to possible rival Mac OS or Windows. Today an operating system must be able to span all the devices that a user may require, a desktop, a phone and a tablet.
I was listening to the Linux Outlaws pod cast and Fab highlighted a truth that Ubuntu, unlike Apple, announced a product but you are unable to go and buy the product at the announcement. The excitement is tempered by the lack of hardware. In the mean time Rim, or as it is now know Blackberry, announced and shipped a touch screen phone the Z10. I was struck by how similar the swipe to the side interface appeared to be when placed side by side with the Ubuntu phone. The hardware was compelling and the software appears to be an engaging experience. One of the Ubuntu phone's advantages over the Blackberry would appear to be its similar approach, to Apple, of an ecosystem which supports it. Integrating the phone with a desktop and tablet. Which the Blackberry may find hard to reproduce seeing as its competition, the Apple phone and Windows phone, all have ecosystems which integrate the phone. They maybe less inclined to help integrate a competitors hardware and software over their own.
