@fmulcar I think we are in line, more or less, and the both of us think that the Nexus 4 is a nice device. For myself i try to be patient with a hope that the Nexus 4 still have a future, but in the meanwhile i stay with the Canonical version.

However, i think that Nexus 4 should have some priority since it had under the wings of Canonical, being their primary device. 🙂
