Re: XMir update for Ubuntu 13.10

Hi Ryein,

For what it's worth, I don't see it as an either or. There is one Ubuntu platform that will support everything from mobile phones, to tablets, to netbooks, to laptops, to work stations, to servers, to clouds, to instances running workloads in those clouds.

Currently, we are playing catch up on phones and tablets, but the goal remains full convergence, full support for all of these from a single code base. In no way is there less of a commitment to desktop users and the integration that you mentioned, we just haven't reached the point where we can really start that integration.

I'm sure we'll have some really good discussions about how to get from here to there at the next UDS, but I hope that sheds some light on the overall goal and the concern you expressed.

Cheers, Rick

Keep up the good work, but maybe you could shed some light on my
