This is a really great step. I previously though Ubuntu was going to ruin itself by getting into the mobile game so late but it seems like their solution might be unified enough (as a result of the time they spent watching others) to actually gain some foothold. I have a Nexus 7 and if they can allow me to dual boot somehow I will be all over this. I'd love to have a little touchscreen Ubuntu PC in my backpack. I'm still not convinced I want it on my phone but they have my attention on the other three screens.
