Comment 1 for bug 1214340

Correction:

12.04 → 14.04 as click isn't supported on unity 7, and then we'll need to support those apps till 14.04 dies in 5 years time.
Then we need a way to transition that from deb to click for 14.10 that'll be fun.................not!!!!!!!
Then from 13.10 onwards there will be click available for apps of a mobile nature initially then in 14.10 we can transition in the desktop apps.

That is at least my understanding of the situation.
