In all seriousness, if he means smartphone from a hardware perspective, I might actually agree. The startup costs there are crazy high.
But, if he means software, no. Ubuntu is doing it and doing it very, very well. I've said it before, and I'll keep saying it. All Android using hardware manufacturers are crazy to continue with Android now that Google owns Motorola. Look at the Moto X. Nothing can compete with it and no one will be able to in the future.
Samsung and the rest should very actively be looking to remove Android from their handsets as quickly as possible. Ubuntu is by far the best choice.
