I watched Jono Bacon's "Crossing the Chasm" presentation from Scale11x last year. I sat through it at Scale, then I rewatched it this afternoon. I missed a key point in the presentation. "Together" It is a community effort to get the convergence strategy to a position that it can cross the chasm of getting mass adoption. I think we in the community are frustrated at how long it takes for this adoption to occur. I was using the X-Windows system in college in 1982, and I am still using it today in the form of xorg.
So I admit that I was a naysayer to Ubuntu Phone, but after watching Jono's talk (again), I finally see what is happening and how Canonical and the Ubuntu community can work together to bring some cool technology to the masses. It is a different path that most of us are used to with commercial/consumer/throw-away products. 2014 is definitely the year of linux on the desktop and maybe on the phone.
