Besides Ubuntu being on my server? They've yet to prove themselves on any device that I'd purchase especially lacking in conventional multi-tasking.

But since you asked nicely; I'd say that Ubuntu is for folks that want an option to iOS and Android. After that, I'd say it'll satisfy the OS tinkerers that wish to fully customize their experience but I've yet to see evidence that's fully the case yet but would not be surprised that's the case.

I'm just not curious about it quite yet but will investigate sooner than later. And your take?
