If Ubuntu had solved the hardware problem in the laptop space already I'd say more power to them. As it is, they really should be cherry picking a limited number of best-of-breed laptop make/models, ensuring support for those and then baking that into their LTS support cycle.

Given the unbelievably more complex hardware environment of handsets, the fact they haven't solved the laptop problem space yet makes me feel like they are biting off more then they can chew.
