why not wait till there's something to talk about
The one comment no one has quoted:
"Yikes, I guess the few minutes of my weekly Q&A hit the news."
I took the time to read the comments because i thought someone who actually knew anything might have said something worth reading. Turns out no.
Fact is, Jono merely mentioned that X wasn't good enough (news to nobody) and that they were evaluating different options (they'd be stupid not to). Nothing terribly new in fact, and certainly nothing worth getting hot and bothered. So why not wait till there's some actual information before having an opinion.
Keep in mind one thing however: Canonical employ intelligent and capable engineers. One expects that whatever decision they take, they'll have some fairly good reasons for it.
( anticipating moans about them dropping Gnome shell for Unity, answer this question honestly - knowing their goal was to build the Unity experience, do you honestly think they could have done it while also aligning development with Gnome shell? (whether you like Unity or not is irrelevant) )
