My thoughts are:
Server: Juju is just plain awesome. If you manage hundreds or thousands of servers, it is Fan-Freakin'-tastic. Seriously, that alone is worth the price of admission.
They backed openstack very early, which looks like the winner. They are THE option for EC2. Heck, even Azure is picking up Ubuntu. More here: http://www.ubuntu.com/cloud If I was deploying in the Cloud, there is no other OS I would choose (and I am). IMO, it would be crazy to not use Ubuntu.
Desktop: Unity is an interesting choice, and if you asked me 3 years ago I would probably have said it was a bad choice, but seeing the state of GNOME these days, it is easily the best choice Canonical has made in the past few years.
And then there are the demo products like Ubuntu for Android, which is just plain awesome. The TV, though I'm not sure how viable it is as a commercial entity, is slick. And there is talk of a phone/tablet. Is there room for a third or fourth person in this market? With the patent problems, probably, I don't know. Though, I have to admit, I'd like to see what an Ubuntu phone and tablet would look like!
