I remember them working on a hybrid OS that would run on your phone or tablet and then you could switch it to desktop mode. Actually looks like they're still working on that

Edit:

seriously guys, can we design product pages so they actually give you a sense of how the product actually works? That page sucks.

I found a video and honestly while I love the idea it seems that the implementation is the worst of both worlds. Who thought that this pull down menu style was a reasonable idea....

Ubuntu Touch isn't a Canonical thing anymore, it's community driven and was picked up by the UBPorts foundation, which is a non-profit.
